Bearing Adapter Sleeves

Bearing Adapter Sleeves

Close gaps between your bearing and shaft for a tight fit

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 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

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

Track Rollers

Support and carry objects as they move along conveyor systems

Splines and Spline Bearings

Splines and Spline Bearings

Transmit rotary power or move loads along the length of splines

Fastening and Joining

Shims

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

Fabricating and Machining

Drill Bushings

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