Bushings install between a rotating drive shaft and a housing to help secure the shaft in place and reduce vibration to extend the working life of hubs and shafts. Quick detachable bushings have a split along one side that eases fitting on shafts of varying diameter. Split taper bushings are flanged with a double-split barrel to provide increased shaft clamping force. Taper lock bushings have a keyway and are installed by pressing the bushing into the bore. Keyless bushings have a smooth, round bore without a keyway or set screw, allowing them to be used in applications that require the direction of shaft rotation to change. Idler bushings provide mountable low-friction rotational support for industrial belt, chain, and geared drive and conveyor systems.
