Vortex Repair, Seal & Shim Kits

Vortex repair kits, seal repair kits, and shim kits for X-Series, XS-Series, XH-Series, and VXT-Series speed reducers. Repair kits provide complete bearing and seal replacements for scheduled maintenance or rebuild work. Seal repair kits provide just the input and output shaft seals for routine seal replacement when bearing replacement isn't yet needed. Shim kits provide the precision-thickness shims used during reducer reassembly to set proper gear backlash and tooth contact pattern. Texas Belting and Supply stocks 17 repair/seal kits across VXT and X-Series sizes, 16 shim kits for X-Series unit sizes 133 through 325, plus the VXT9 Input Shaft Kit.

Applications

Typical applications for Vortex repair, seal & shim kits:

• Scheduled preventive maintenance: replacing seals before they leak (typically every 3-5 years on continuous duty)
• Reactive repair: addressing a confirmed leaking output or input seal in service
• Complete rebuild: replacing both bearings and seals during major overhaul (every 7-10 years typical)
• Reassembly after housing or gear inspection: shim kits provide the precision spacers needed to re-set backlash
• Conveyor downtime minimization: keeping spare repair kits on hand for fast turnaround

Frequently Asked Questions

Repair kit vs Seal repair kit?

Full repair kits (RK) include bearings, seals, and gaskets for complete rebuild. Seal repair kits (SRK) include only the input and output shaft seals plus the housing gaskets, for less invasive seal-only replacement. Choose RK for full overhaul, SRK for seal-only maintenance.

Which size do you need?

Match the kit number to your reducer unit size. For X-Series reducers, use 133RK or 133SRK for X133/XS133/XH133, 154 for size 154, and so on through 325. For VXT reducers, use the corresponding size: 2RK for VXT2 through 10RK for VXT10.

When do you need a shim kit?

Shim kits are used during reducer reassembly after disassembly for inspection or repair. The shim kit provides the precision-thickness washers placed between bearing races and housing shoulders to set proper bearing preload and gear backlash. A reducer rebuilt without correct shim adjustment may run noisy or wear prematurely.

What reducer family is each repair, seal, or shim kit 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 repair, seal & shim kits 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.
