Vortex C-Face Input Flange Adapters

Vortex C-Face input flange adapters for VR-Series inline helical reducers and X-Series worm gear reducers. The input flange adapts the reducer to accept a different NEMA C-face motor frame than the unit was originally configured for. Mount a 56C motor on a unit built for 140TC, or convert an X-Series worm gear reducer to NEMA C-face input. Texas Belting and Supply stocks 5 VR-Series input flanges (sizes 56C through 250TC) and 8 X-Series input flanges (XIF series for X-Series unit sizes 133 through 325, in 56C, 140TC, and 180TC motor frames).

Applications

Typical applications for Vortex c-face input flange adapters:

• Adapting a reducer designed for one NEMA C-face motor frame to accept a different motor frame
• Converting an X-Series worm gear reducer with solid input shaft to direct NEMA C-face motor mounting
• Replacement of a worn or damaged input flange on an existing installation
• Standardizing motor frame sizes across a plant's reducer fleet for inventory simplification
• Re-motoring an installation to a different HP rating that requires a different NEMA frame

Frequently Asked Questions

Which reducer family is the flange for?

VR- prefix flanges (VR-56C, VR-140TC, etc.) are for VR-Series inline helical reducers. XIF prefix flanges (XIF133/154-56C, XIF237/262-140TC, etc.) are for X / XS / XH-Series worm gear reducers.

Which NEMA frame do you need?

Available NEMA C-face frames: 56C (1/3 to 1.5 HP typical), 140TC (1 to 3 HP), 180TC (5 to 7.5 HP), 210TC (10 to 15 HP), 250TC (20 to 25 HP). Match the frame to your motor.

XIF flanges cover multiple unit sizes:

Each XIF kit covers a range of X-Series unit sizes (e.g., XIF133/154-56C fits both X133 and XS133 and X154 and XS154). This reduces SKU count and simplifies inventory. Check the size range stamped on the kit to confirm fit.

What reducer family is each input flange adapter for?

Each accessory in this collection is labeled with the reducer family it fits (X-Series, VXT-Series, VR-Series, or VMRV-Series). Filter by reducer family or browse by accessory type. Each product page also indicates the specific reducer size and configuration the accessory matches.

Does Texas Belting and Supply ship from Houston?

Yes. All Vortex c-face input flange adapters in our active inventory ship from Texas Belting and Supply's Houston, TX warehouse the same business day for orders placed before 3 PM Central time, subject to current inventory. Non-stocked configurations may have a 1-3 business day lead time. Call (888) 203-2358 to confirm current stock for any specific part.

How do I know which size accessory I need?

Match the accessory to your existing reducer. The accessory part number prefix tells you the family (VXT vs X-Series vs VMRV vs VR). The number in the SKU tells you the unit size (2-12 for VXT, 30-110 for VMRV, 133-325 for X-Series). If you cannot identify your reducer's exact specification, call (888) 203-2358 with the existing reducer's nameplate information and we will help you spec the right accessory.
