    Steel

    The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered sprockets and pulleys of the same bushing trade number. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.

When you tighten the included screws, the bushing's inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear. They can be mounted on shafts with or without keyways.
