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

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

Roller Bearing Shaft Liners

Roller Bearing Shaft Liners

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

Thrust Roller Bearing Washers

Thrust Roller 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

Bronze

Better wear resistance than copper and brass—all with material certificates for traceability

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Plastic

A lightweight alternative to metal and glass

Fastening and Joining

Shims

Align and space components on shafts, or level machinery, cabinets, and doors
