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

Swivel Joints

Handle shaft misalignment where ball joint rod ends won’t fit; also known as spherical bearings

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

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

Lead Screws and Nuts

Lead Screws and Nuts

Components travel along a screw with broad, square threads to clamp and lift heavy loads

Raw Materials

Bronze

Better wear resistance than copper and brass—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
