About This Unit
The Vortex VMRV-50 follows the IEC metric worm gear standard, with center distance designated in millimeters and motor frames using NEMA C-face mounting. The die-cast aluminum housing provides corrosion resistance and appropriate strength for the 1 to 2 HP torque class. Synthetic gear oil supports service from minus 20 to 200 degrees Fahrenheit, suiting indoor, outdoor protected, and washdown applications.
This unit is the direct Vortex replacement for the Motovario NMRV-050-5 reducer, with full dimensional interchange at the same IEC size, ratio, and motor frame. It also cross-references to Bonfiglioli VF, SEW-Eurodrive S-Series, STM Italy RV/RT, and other IEC metric worm gear brands. Typical applications include conveyor drives, packaging machinery, mixers, and OEM equipment built to European metric standards.
Frequently Asked Questions
What does the Vortex VMRV-50-5-56C replace?
This unit is the direct Vortex equivalent for Motovario NMRV-050-5 at NEMA 56C motor frame. It also cross-references dimensionally to Bonfiglioli VF-50, SEW-Eurodrive S-Series at 50 mm center distance, STM Italy RV-50, and other IEC metric worm gear brands at the same size and ratio. Match motor frame designation (NEMA C-face vs IEC B5/B14) and output configuration when substituting.
What accessories do I need for the VMRV-50?
The VMRV-50 ships with a hollow output bore. Depending on your driven equipment, you may also need: an output flange (VMRV-50 OSF) to convert to flange-mount output, a single-ended solid output shaft (VMRV-50 OSS), a double-ended output shaft (VMRV-50 OSD), a cover (VMRV-50 CVR) for the unused output side, or a torque arm (VMRV-50 TA) when the unit is mounted directly on the driven shaft via the hollow bore. All accessories are sold separately.
