Power Transmission

Ball Bearings

Create less friction than other bearings for use at high speeds

Roller Bearings

Roller Bearings

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

Sleeve Bearings

Sleeve Bearings

With no moving parts, the plainest type of bearing

Thrust Bearings

Thrust Bearings

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

Flanged Sleeve Bearings

Flanged Sleeve Bearings

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

Pivot Bearings

Best for applications that require small, precise oscillating motion with limited twisting

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

Mounted Bearings

Mounted Bearings

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

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

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

Fabricating and Machining

Router Guides

Make precise circular or intricate cuts with routers
