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


Flanged Sleeve Plain Bearings	Sleeve Plain Bearings

Acetal bearings are a good choice for washdown and dusty environments.

Plain Bearing—Plain bearings prevent wear to the wheel bore.

Roller Bearings

Ball Bearings—Ball bearings require minimal effort to start rolling and are best for low speeds.

Roller Bearings—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

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.

Bench and Pedestal Grinding Wheel Reducer Bushings


Bushing Shown with Wheel (Not Included)

Insert these bushings into the arbor hole of your grinding wheel to attach wheels to smaller diameter shanks.

The smallest shank diameter size listed is the smallest allowed for that size wheel.

Hex Flanged Eccentric Bushings

Often used with V-groove wheels or track roller carriages, these off-center bushings create precise mounting clearance. As you turn the bushing’s hex flange with a wrench, it adjusts the distance between the V-groove wheel or carriage and the rail. Tighten the axle bolt in place once you’ve adjusted them. Made of 303 stainless steel, these bushings have very good corrosion resistance.

Wheel Brush Arbor Hole Reducers

Reduce the arbor hole size of a wheel brush so that it fits the shaft of your tool.

Steel

Steel reducers come in pairs. To install, snap a reducer into the arbor hole on both sides of the wheel brush.
