About Roller Chain and Sprockets

ANSI Roller Chain and Links for Flat-Belt Pulleys
Also known as leaf chain and counterbalance chain, this chain is used with pulleys rather than sprockets for low-speed pulling and as counterweight chain for machine tools, elevator and oven doors, and forklift masts. Made of interlaced plates held together by rivet pins, it has a higher tensile strength than roller chain and is used with flat pulleys instead of sprockets.
When servicing worn leaf chain, replace the entire chain—do not splice chains together or mix old and new chain.
ISO 4347 chain meets an international standard for leaf chain.

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 size 04B and 05B, an additional connecting link is required to join them to chain. For trade size 06B and up, the side plate is easy to remove for attaching them to chain.
