Quick-Grip Screw-Clamp Bushings
Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed. As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.

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. Made of spring steel, they flex under stress and shock and can handle oscillating or slow rotational motion.
