With metric teeth and slim profile, these sprockets allow your ISO roller chain to reach narrow spaces. They're commonly referred to as A-plate sprockets. Machine the unfinished bore to fit your shaft—sprockets come machined to the shaft diameter listed and are machinable up to the maximum shaft diameter size. Sprockets meet DIN 8187 and ISO 606, international standards for sprockets and roller chains.

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.
