Self-Centering Screw-Clamp Bushings

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

Quick-Grip Screw-Clamp Bushings

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

Flush-Mount Screw-Clamp Bushings

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

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.

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.

Quick-Disconnect (QD) Bushings

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

Taper-Lock Bushings

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

Vibration-Damping Flexible Shaft Couplings

A flexible tire on these couplings safeguards components on your shafts by reducing vibration and shock.

Drill Bushings

Removable Drill Bushings

Replace worn bushings and quickly change IDs without needing to repeatedly use a lever press. Instead of pressing bushings in and out of your jig fixture, which can cause damage, these bushings slide in and out of sleeves.

Made-to-Order Removable Drill Bushings

Choose the ID, OD, and length you need.

Lock Rings for Drill Bushings for Thin Metal

Twist these lock rings onto bushings to secure them in drilled holes.

Removable Drill Bushings for Thin Metal

Insert these bushings into a drilled hole and twist the lock ring to secure. Reusable and easy to replace, they are held in in place by a separate locking part.
