Designed to meet ISO 606 and DIN 8187 international dimensional standards, these sprockets are for use with compatible ISO and DIN roller chain. They come machined to the shaft diameter size listed and are machinable up to the maximum shaft diameter size.

Sprockets for Double-Strand Metric Roller Chain

The double row of teeth on these sprockets are designed to fit into metric ISO double-strand roller chain. They have an unfinished bore that’s machined to the shaft diameter size listed. Machine them to fit any shaft up to the maximum shaft diameter size. The extended hub makes these sprockets more stable and more durable than flat sprockets. They meet ISO 606 (formerly DIN 8187), which is an international standard for sprocket and roller chain dimensions and materials.

Taper-Lock Bushing-Bore Sprockets for Metric Roller Chain

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.
