A tapered bushing, also identified as a tapered lock bushing, is a tapered, non-flanged, break up bushing whose tapered sleeve is possibly screwed or tightened with a socket head cap screw and squeezed on to the shaft so that It is mounted on the shaft. Protects a wide variety of pulleys, sprockets, flanged hubs, and couplings. These bushings are used in pulleys and sprockets to increase clamping power, even though standard bore products lock onto the shaft only with a keyway and set screw. All bushings provided by EP are separately manufactured of higher-good quality material and boxed grub screws.
