Power Transmission

Ball Bearings

Create less friction than other bearings for use at high speeds

Flanged Sleeve Bearings

Flanged Sleeve Bearings

A sleeve and thrust bearing in one to support both parallel and perpendicular loads

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Roller Bearings

Roller Bearings

Support higher loads than ball bearings, but run at lower 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

Mounted Bearings

Mounted Bearings

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

Shaft Collars

Hold and position parts on a shaft, or limit shaft movement

Drive Rollers

Transmit power from motors to systems like conveyors; also known as contact wheels and feed rollers

Lead Screws and Nuts

Lead Screws and Nuts

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