While their teeth fit into metric ISO roller chain, these sprockets use taper-lock bushings to grip shafts. That means you can switch to a different diameter shaft by changing the bushing instead of machining the sprocket. Bushings mount flush inside these sprockets; secure them in place by tightening the set screws included with the bushings. These sprockets have an extended hub that makes them more stable and durable than flat sprockets. All meet ISO 606 (formerly DIN 8187), which is an international standard for sprocket and roller chain dimensions and materials.
