Quick disconnect bushings and hubs are simple, easy-to-install bushings used to mount pulleys, sprockets, and sheaves on shafts. They are split to provide strong clamping force and a precise fit. Easy to adjust, these flanged bushings are keyed to prevent the shaft from rotating in the bushing. A set screw then stops the key from moving during drive operation. Short quick disconnect bushings feature a shallow keyseat for weld-on hubs.
