Wheel Bearings
Replace worn or damaged wheel bearings to keep your equipment rolling. Use flanged bearings and ball bearings in pairs. Change the axle diameter with wheel reducer bushings (sold separately).
Note: Not for use in towing applications.
For impact-resistant tapered roller bearings, as well as other bearing materials and sizes, please see Ball and Roller Bearings and Sleeve Bearings.
Acetal bearings are a good choice for washdown and dusty environments.
Plain bearings prevent wear to the wheel bore. Ball bearings require minimal effort to start rolling and are best for low speeds. Roller bearings provide smooth rolling.
Retaining washers hold roller bearings in place.

Wheel Reducer Bushings
Reduce the inside diameter of a bearing to fit a particular axle size. Also known as spanner bushings, they also reduce wear on the axle when used in plain bores and with straight roller bearings. All have a hole for lubrication.
Washers slide over the bushing and add 3/32" to the hub length of your wheel. Multiple washers can be used to match the length of the bushing.

Skate Wheels
Replace damaged wheels or use multiple wheels to build a custom conveyor.
Steel wheels are stronger than aluminum wheels. Style C wheels have a hollow core, making them lightweight—use them to distribute the weight of a load evenly. Style D wheels are steel threaded. They’re designed for use in push-back racks where skids are pushed back and up the incline conveyor. Rather than riding on an axle, these wheels are bolted.
Aluminum wheels are lightweight and corrosion resistant. Stainless steel wheels have more corrosion resistance than steel wheels and greater strength than aluminum wheels. Acetal wheels are abrasion resistant. Nylon wheels are nonmarking and quieter than metal. ABS wheels are nonmarking, acid resistant, and quieter than metal. Polycarbonate wheels have high capacities and good impact resistance. Fiberglass wheels are stronger than nylon and withstand washdowns and harsh environments.

Multidirectional Skate Wheels
These wheels have rollers that rotate around the wheel core to allow movement in any direction.
Wheels with a plain bore rotate freely around an axle or shaft. Wheels with a keyed bore rotate with the shaft instead of around it. This means multiple wheels placed along a shaft will rotate in sync for smooth travel. They can also be driven with a motor connected to the keyed shaft. Wheels with a bushing bore roll more smoothly than those with a plain bore. The bushing within the wheel acts as a bearing and has less friction when it spins. The bushings are plastic, so they won’t corrode.
Wheels with two or three wheels have increased surface area, so they are stable, smooth, and less likely to slip than single wheels.
Acetal wheels resist abrasion. ABS wheels are nonmarking and acid resistant. Polyurethane wheels combine the abrasion resistance of plastic with the shock-absorbing qualities of rubber.
