301 Products

Power Transmission

Mounted Bearings

Mounted Bearings

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

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

Bearing Shaft Liners

Bearing Shaft Liners

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

Bearing Washers

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

Drive Rollers

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

Shaft Collars

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

Material Handling

Screw Conveyors

Screw Conveyors

Push material through fixed troughs

Fastening and Joining

Shims

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