Machinable-Bore Corrosion-Resistant Sprockets for Metric Roller Chain

Machine the center of these sprockets to fit the exact dimensions of your shaft. They come machined to the shaft diameter size listed and are machinable up to the maximum shaft diameter size. The teeth are sized to fit into metric ISO roller chain. Made from stainless steel, they won’t corrode from humidity or frequent washdowns. The extended hub makes these sprockets more stable and more durable than sprockets with flat hubs. They meet ISO 606 (formerly DIN 8187), which is an international standard for dimensions and materials.

Flat Sprockets for Metric Roller Chain

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.

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.

Idler Sprockets for Metric Roller Chain

Keep constant tension on your drive with these sprockets that press against your metric ISO roller chain to take up slack and reduce wear and vibration. They rotate freely on built-in ball bearings, which are double sealed to keep dirt out, and are for use with roller chain tensioners. All come with a finished bore that fits directly onto your shaft—no need for machining. These sprockets meet ISO 606, which is an international standard for 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.
