Quick-Disconnect (QD) Bushings
The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys. Bushings fit quick-disconnect (QD) sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

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.
