Power Transmission

Mounted Bearings

Mounted Bearings

Ball, roller, and sleeve bearings ready to bolt in place

Ball Bearings

Create less friction than other bearings for use at high speeds

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Flanged Sleeve Bearings

Flanged Sleeve Bearings

A sleeve and thrust bearing in one to support both parallel and perpendicular loads

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Linear Bearing Housings

Linear Bearing Housings

Hold linear ball or sleeve bearings by sliding them in and securing with retaining rings

Roller Bearings

Roller Bearings

Support higher loads than ball bearings, but run at lower speeds

Thrust Bearings

Thrust Bearings

Support loads parallel to the shaft with plain, ball, or roller bearings

Bearing Housings

Bearing Housings

Mount your own bearings in place

Linear Bearing Brakes

Linear Bearing Brakes

Lock bearings in place on a shaft for precise positioning

Pivot Bearings

Best for applications that require small, precise oscillating motion with limited twisting

Ball Splines and Bearings

Ball Splines and Bearings

Combine ball splines and bearings to create linear and rotary motion systems

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

Mount between a rotating shaft and equipment to secure the shaft and reduce vibration

Sleeve Splines and Bearings

Sleeve Splines and Bearings

Combine sleeve splines and bearings to create linear and rotary motion systems

Bore Reducers

Adapt the bore of a component to a smaller size for mounting on a shaft

Material Handling

Conveyor Roller Bearings

Conveyor Roller Bearings

Replace bearings on conveyor rollers, or press into tubing or pipe to create a roller

Wheel Bearings

Reduce friction between the axle and the wheel for smooth movement

Wheel Reducer Bushings

Wheel Reducer Bushings

Reduce the inside diameter of a bearing to fit a particular axle size

Building and Machinery Hardware

Grommets

Protect wire, cable, and cords from holes with sharp or rough edges

Fastening and Joining

Washers

Nearly every size and shape imaginable, from flat washers to clipped to curved
