Quick-Disconnect (QD) Bushings
Use these bushings to make the same sprocket or pulley compatible with multiple shaft diameters. They fit quick-disconnect(QD) sprockets and pulleys of the same bushing style. As you tighten the included cap screws, the bushing grips the shaft and pulls it into the sprocket or pulley. Bushings are steel or cast iron.
Depending on the bore size you choose, the bushing will have the corresponding keyway listed below. Bushings with a standard ANSI or ISO keyway do not come with a key. Bushings with a shallow keyway come with a key.If you’re not sure email or call us for help firstname.lastname@example.org
