Inline helical reducers are used wherever a fixed speed reduction is needed in a compact, high-efficiency package: belt and roller conveyors, packaging machinery, mixers, blowers, and OEM machinery. Helical gear teeth carry load more efficiently than worm gears, so VR reducers typically run at 95% or higher mechanical efficiency, generate less heat, and have higher torque capacity per unit size than equivalent worm gear reducers.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:18px;font-weight:600 !important;margin-top:24px;margin-bottom:8px;\"\u003eHow do I read a Vortex VR part number?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eVR part numbers follow the format VR[size]-[ratio]-[motor frame]. Take VR28-10-140TC as the example. VR identifies the series. 28 is the Vortex unit size (size 28, a fractional through 1 HP class reducer). 10 is the nominal gear ratio (10:1, with an exact ratio of 10.13:1). 140TC is the NEMA C-face motor frame that the input flange accepts.

Inline helical uses parallel helical gear teeth, with input and output shafts on the same axis. Worm gear uses a worm screw and gear arrangement, with output shaft at 90 degrees to input. Inline helical advantages: higher mechanical efficiency (typically 95% or above versus 50 to 90% for worm), higher torque capacity per unit size, less heat generation, longer service life. Worm gear advantages: lower cost at small sizes, inherent self-locking at higher ratios, quieter operation. Choose VR-Series when efficiency, torque density, and heat are the priorities; choose worm gear when cost, footprint, or self-locking is the priority.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:18px;font-weight:600 !important;margin-top:24px;margin-bottom:8px;\"\u003eWhat sizes and ratios are available?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThe VR-Series is available in eight unit sizes (VR28, VR38, VR48, VR58, VR68, VR78, VR88, VR98) covering fractional through 20 HP applications.

VR38 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR38-10-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 10:1 ratio in the VR38 size class (1 through 2 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR38 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR38-10-56C ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR28 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR28-25-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 25:1 ratio in the VR28 size class (fractional through 1 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio.

The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled.

VR28 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR28-30-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 30:1 ratio in the VR28 size class (fractional through 1 HP).

VR48 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR48-50-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 50:1 ratio in the VR48 size class (2 through 3 HP).

VR38 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR38-15-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 15:1 ratio in the VR38 size class (1 through 2 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR38 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR38-15-180TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR28 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 140TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR28-5-140TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 140TC mounted inline helical reducer at 5:1 ratio in the VR28 size class (fractional through 1 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio.

The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR28-5-140TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR28 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR28-15-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 15:1 ratio in the VR28 size class (fractional through 1 HP).

VR78 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR78-20-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 20:1 ratio in the VR78 size class (7.5 through 10 HP).

VR48 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR48-20-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 20:1 ratio in the VR48 size class (2 through 3 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR48 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR48-20-56C ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR38 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 140TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR38-10-140TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 140TC mounted inline helical reducer at 10:1 ratio in the VR38 size class (1 through 2 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio.

The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR38-10-140TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR38 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 140TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR38-5-140TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 140TC mounted inline helical reducer at 5:1 ratio in the VR38 size class (1 through 2 HP).

VR48 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR48-56-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 56:1 ratio in the VR48 size class (2 through 3 HP).

VR28 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR28-45-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 45:1 ratio in the VR28 size class (fractional through 1 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR28 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR28-45-56C ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR58 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR58-15-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 15:1 ratio in the VR58 size class (3 through 5 HP).

VR68 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR68-35-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 35:1 ratio in the VR68 size class (5 through 7.5 HP).

VR38 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR38-50-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 50:1 ratio in the VR38 size class (1 through 2 HP).

VR48 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 140TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR48-30-140TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 140TC mounted inline helical reducer at 30:1 ratio in the VR48 size class (2 through 3 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR48 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR48-30-140TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR28 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 140TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR28-10-140TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 140TC mounted inline helical reducer at 10:1 ratio in the VR28 size class (fractional through 1 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR28 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR28-10-140TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR28 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR28-50-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 50:1 ratio in the VR28 size class (fractional through 1 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio.

The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR28-50-56C ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR38 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR38-15-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 15:1 ratio in the VR38 size class (1 through 2 HP).

VR78 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR78-10-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 10:1 ratio in the VR78 size class (7.5 through 10 HP).

VR38 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR38-25-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 25:1 ratio in the VR38 size class (1 through 2 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR38 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR38-25-56C ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing.

The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled.

VR68 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR68-30-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 30:1 ratio in the VR68 size class (5 through 7.5 HP).

VR48 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR48-10-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 10:1 ratio in the VR48 size class (2 through 3 HP).

VR58 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 140TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR58-20-140TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 140TC mounted inline helical reducer at 20:1 ratio in the VR58 size class (3 through 5 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR58 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR58-20-140TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR68 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 140TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR68-100-140TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 140TC mounted inline helical reducer at 100:1 ratio in the VR68 size class (5 through 7.5 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR68 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR68-100-140TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR58 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR58-80-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 80:1 ratio in the VR58 size class (3 through 5 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio.

The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR58-80-56C ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR68 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR68-45-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 45:1 ratio in the VR68 size class (5 through 7.5 HP).

VR68 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR68-25-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 25:1 ratio in the VR68 size class (5 through 7.5 HP).

VR28 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 140TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR28-20-140TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 140TC mounted inline helical reducer at 20:1 ratio in the VR28 size class (fractional through 1 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio.

The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR28-20-140TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR58 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR58-20-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 20:1 ratio in the VR58 size class (3 through 5 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR58 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR58-20-180TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR78 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 180TC motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR78-25-180TC replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 180TC mounted inline helical reducer at 25:1 ratio in the VR78 size class (7.5 through 10 HP). It cross-references dimensionally to inline helical reducers from SEW-Eurodrive, Sumitomo, Nord, Bonfiglioli, Falk, Stober, and other major manufacturers at matching motor frame and ratio. Match the existing reducer's motor frame, output shaft diameter, gear ratio, and overall dimensions against the downloadable VR78 spec sheet to confirm fit.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhy choose inline helical over a worm gear reducer for this application?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eInline helical reducers like the VR-Series typically run at 95% or higher mechanical efficiency versus 50 to 90% for worm gear reducers, which means less energy loss to heat, longer service life, and the ability to drive larger loads from a smaller motor. The inline configuration also keeps the output shaft on the same axis as the motor, which is preferable in pumps, blowers, and any installation where the driven shaft was previously direct-coupled. Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\u003c\/p\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eDoes the Vortex VR78-25-180TC ship from Houston?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eYes.

VR38 is a single or multi-stage helical gear reducer housed in a cast iron case. Input is a NEMA C-face flange that bolts a standard 56C motor directly to the unit; output is a coaxial solid shaft with a keyway. Helical gear teeth engage gradually rather than abruptly, which produces smoother operation, lower noise, and higher load capacity per unit size than spur or worm gearing. The synthetic gear oil charge supports service temperatures from minus 20 to 200 degrees Fahrenheit, suiting the VR-Series to indoor, outdoor protected, and washdown applications.\u003c\/p\u003e\n\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eTypical applications: belt and roller conveyors, packaging machinery, mixers and agitators, blowers and fans, pump drives, and OEM machinery requiring a compact high-efficiency inline gearbox.\u003c\/p\u003e\n\n\u003ch2 style=\"color:#1e2d4d !important;font-size:22px;font-weight:600 !important;margin-top:36px;margin-bottom:12px;\"\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3 style=\"color:#1e2d4d !important;font-size:17px;font-weight:600 !important;margin-top:20px;margin-bottom:8px;\"\u003eWhat does the Vortex VR38-30-56C replace?\u003c\/h3\u003e\n\u003cp style=\"line-height:1.6;margin:0 0 16px 0;\"\u003eThis is a NEMA 56C mounted inline helical reducer at 30:1 ratio in the VR38 size class (1 through 2 HP).

Worm gear is the better choice when budget is the primary constraint, when self-locking output is needed, or when a 90-degree offset is required.\"}}, {\"@type\": \"Question\", \"name\": \"Does the Vortex VR38-30-56C ship from Houston?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
