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.

Metric Roller Chain and Links
This chain conforms to ISO 606B and is compatible with BS 228 (British standard) and DIN 8187 (German standard).
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 a chain. Adding-and-connecting links are also known as half links and offset links. They can join chain that requires an odd number of links. For trade number 06B and up, the side plate is easy to remove for attaching them to chain.
