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.

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.

Bore Reducers

Instead of replacing your shaft or keeping components, such as couplings, with various bore diameters on hand, these reducers adapt the bore of a component to a smaller size.

Vibration-Damping Flexible Shaft Couplings

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