Ball Bearings

Create less friction than other bearings for use at high speeds

Thrust Bearings

Thrust Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Linear Bearing Housings

Linear Bearing Housings

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

Linear Bearing Brakes

Linear Bearing Brakes

Lock bearings in place on a shaft for precise positioning

Carriages and Guide Rails
