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

Mounted Bearings

Mounted Bearings

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

Flanged Sleeve Bearings

Flanged Sleeve Bearings

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

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

Rod Ends

Use with connecting rods to support loads and control steering, tensioning, or pivoting motion

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

Swivel Joints

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

Track Rollers

Support and carry objects as they move along conveyor systems

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

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

Building and Machinery Hardware

Grommets

Protect wire, cable, and cords from holes with sharp or rough edges

Raw Materials

Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments—all with material certificates for traceability
