With a slim profile and a double row of teeth, these sprockets allow your metric ISO double-strand roller chain to fit into tight spaces. They’re often called A-plate sprockets. To grip shafts, they use taper-lock bushings, so 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. All of these sprockets meet ISO 606 (formerly DIN 8187), which is an international standard for sprocket and roller chain dimensions and materials.
