Power Transmission

Roller Bearings

Roller Bearings

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

Thrust Bearings

Thrust Bearings

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

Linear Bearings

Linear Bearings

Minimize friction as parts move along a shaft

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

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

Linear Bearing Housings

Linear Bearing Housings

Hold linear ball or sleeve bearings by sliding them in and securing with retaining rings

Swivel Joints

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

Rod End Inserts

Rod End Inserts

Attach to rod ends to increase the amount of misalignment they can handle

Rod End Seals

Keep dirt out and lubrication in to extend the life of rod ends

Pulley and Sprocket Bushings

Pulley and Sprocket Bushings

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

Raw Materials

Steel

Strong, machinable, and weldable—all with material certificates for traceability

Plastic

A lightweight alternative to metal and glass

Bronze

Better wear resistance than copper and brass—all with material certificates for traceability

Fabricating and Machining

Drill Bushings

Fit in holes to guide drill bits and other cutting tools for precise and repeatable holes and cuts

Fastening and Joining

Shims

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

Material Handling

Wheel Reducer Bushings

Wheel Reducer Bushings

Reduce the inside diameter of a bearing to fit a particular axle size
