Power Transmission

Ball Bearings

Create less friction than other bearings for use at high speeds

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Flanged Sleeve Bearings

Flanged Sleeve Bearings

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

Mounted Bearings

Mounted Bearings

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

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

Roller Bearings

Roller Bearings

Thrust Roller Bearing Washers

Thrust Roller Bearing Washers

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

Idler Rollers

Guide boxes and parts as they pass through conveyor systems

Drive Rollers

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

Track Rollers

Support and carry objects as they move along conveyor systems

Shaft Collars

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

Positioning Slides

Positioning Slides

A lead screw drives the carriage for accurate positioning in laboratory and production equipment

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

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

Bore Reducers

Adapt the bore of a component to a smaller size for mounting on a shaft
