How can we improve?

406 Products

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

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

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

Bearing Housings

Bearing Housings

Mount your own bearings in place

Bearing Lock Washers

Bearing Lock Washers

Lock bearing nuts in place to prevent loosening due to vibration

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

Drive Rollers

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

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

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

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
