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.

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.

Heavy Duty Metric Roller Chains and Links




Designed for long-lasting durability, this metric chain has thick side plates that resist wear and fatigue. It also has end-softened pins, which make it easy to disassemble. It meets ISO 606B, which is an international standard for dimensions and materials.
Connecting links are also known as master links. They're used to join the ends of a chain length. The side plate is easy to remove for attaching to chain.
Adding-and-connecting links are also known as half links and offset links. Use them to join chain that requires an odd number of links. The side plate is easy to remove for attaching to chain.
