Power Transmission

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

Mounted Bearings

Mounted Bearings

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

Thrust Bearings

Thrust Bearings

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

Pivot Bearings

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

Roller Bearings

Roller Bearings

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

Linear Bearing Housings

Linear Bearing Housings

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

Thrust Roller Bearing Washers

Thrust Roller Bearing Washers

Adapt needle-roller thrust bearings for use on unhardened, unground surfaces

Ball Splines and Bearings

Ball Splines and Bearings

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

Sleeve Splines and Bearings

Sleeve Splines and Bearings

Transmit rotary power or move loads along the length of splines

Material Handling

Wheel Bearings

Reduce friction between the axle and the wheel for smooth movement

Conveyor Roller Bearings

Conveyor Roller Bearings

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