About Roller Chain and Sprockets

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 06B and up, the side plate is easy to remove for attaching them to chain.

Maintenance-Free Metric Roller Chain and Links

Chain

Connecting Link

Adding-and-Connecting Link

With self-lubricating pins and bushings, this metric roller chain requires less maintenance than standard roller chain. It’s commonly used in lubrication-sensitive processing facilities for food and beverage, paper, and textiles.

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.

Hollow-Pin Metric Roller Chain and Links

Chain

Connecting Link

Connect attachments to this metric chain without disassembling it. In addition to letting you add attachments with extension pins or rods for conveyance or elevation applications, the hollow pins on this chain weigh less than standard pins. Made of steel, this chain resists wear and handles higher loads than stainless steel chain. It conforms to ISO 606B and is compatible with BS 228, a British standard, and DIN 8187, a German standard.

Connecting links are 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.
