Vortex Screw Conveyor Drive Components

Vortex drive shafts, flange adapters, and shaft removal wedges for VXT-Series shaft mount reducers driving CEMA standard screw conveyors. The screw conveyor drive shaft connects the VXT output bore to the screw conveyor's trough end via a tapered bushing system. The drive flange replaces the conventional CEMA trough-end bearing assembly when the VXT is direct-mounted on the screw conveyor. The shaft removal wedge is the dedicated tool for breaking the tapered shaft free from the bushing during service. Texas Belting and Supply stocks 22 drive shafts (VXT sizes 2-7, screw shaft bores 1 1/2 through 3 inches), 6 drive flanges (VXT sizes 2-7), and 6 shaft removal wedges (VXT sizes 2-7).

Applications

Typical applications for Vortex screw conveyor drive components:

• New screw conveyor drive builds where a VXT reducer drives the screw directly via the drive shaft and flange
• Replacement of a damaged drive shaft on an existing VXT-on-screw-conveyor installation
• Replacement of the trough-end flange on an existing installation
• Service work: using the shaft removal wedge tool to break the tapered shaft free from the VXT bore
• OEM screw conveyor manufacturers building VXT-driven units to CEMA standards

Frequently Asked Questions

Match the VXT size to the components:

The drive shaft, drive flange, and removal wedge are all size-matched to your VXT. 2SCDS, 2SCF, and 2SCRW fit VXT2; 5SCDS, 5SCF, and 5SCRW fit VXT5, and so on. Within each VXT size, the drive shaft is also sized for your screw conveyor's shaft bore (1 1/2, 2, 2 7/16, or 3 inches).

Drive shaft bore size matches your screw conveyor shaft:

CEMA standard screw conveyor shaft sizes are 1 1/2, 2, 2 7/16, 3, 3 7/16, 3 15/16, and 4 7/16 inches. The drive shaft you select must match your existing screw conveyor's shaft size. Common matches: VXT2 drives typically use 1 1/2 or 2 inch shafts; VXT5 drives use 2 7/16 or 3 inch shafts.

Do you need the shaft removal wedge?

Yes, if you anticipate ever needing to service the drive. The tapered fit between the VXT bore and the drive shaft is intentional (it transmits torque) but it requires a wedge tool to release for service. Most maintenance shops keep one per VXT size on hand.

What reducer family is each screw conveyor drive component 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 screw conveyor drive components 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.
