Power Transmission

Roller Bearings

Roller Bearings

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

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

Thrust Bearings

Thrust Bearings

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

Bearing Shaft Liners

Bearing Shaft Liners

Adapt precision needle-roller bearings for use on unhardened, unground shafts

Bearing Washers

Bearing Washers

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

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

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

Raw Materials
