Self-Centering Screw-Clamp Bushings
A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket. They are also good for shock loads. 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.
