Taper-Lock Bushings
Mount these hubless bushings flush into your sprocket or pulley for a slim profile with no protruding screws. They are for use with taper-lock sprockets of the same bushing style. As you tighten the included set screws, the bushing grips the shaft and pulls it into your sprocket or pulley.
