These bearings have a ceramic liner to help them achieve high speeds as well as rapid acceleration and deceleration.

Threaded Adapters for Pullers

Use adapters on the ends of forcing screws and face-grip puller legs when pulling shafts, bearing caps, and pinions.

Bushings for Chain and Belt Drives

Quick-Grip Screw-Clamp Bushings

Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed.

Self-Centering Screw-Clamp Bushings

A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket.

Flush-Mount Screw-Clamp Bushings

Insert these bushings into the bore of your sprocket for flush or recessed mounting.

Light Duty Sleeve Bushings

Reduce the ID of sprockets, pulleys, and gears in low-torque applications.

Self-Adjusting Spring Bushings

A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit.

Hex Flanged Eccentric Bushings

Often used with V-groove wheels or track roller carriages, these off-center bushings create precise mounting clearance.

Quick-Disconnect (QD) Bushings

The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys.

Split-Tapered Bushings

The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings.

Taper-Lock Bushings

Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws.

Thread Adapters for Drum Openings

Convert drum openings with metric or BSPP threads to a 2 NPT pipe size.
