ANSI Roller Chain and Links
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 links are also known as roller links. They require two connecting links to join chain. Adding-and-connecting links are also known as half links and offset links. A combination of connecting and adding links, they join chain that requires an odd number of links. For trade number 35 and up, the side plate is easy to remove for attaching them to chain.

Sprockets for Triple-Strand ANSI Roller Chain
Three rows of teeth make these sprockets compatible with triple-strand ANSI roller chain. The teeth are hardened steel, so they resist wear better and last longer than standard steel teeth. For a custom fit on your shaft, machine these sprockets to your exact specifications. They come machined to the shaft diameter listed and are machinable up to the maximum shaft diameter size.

Floating Roller Chain Tensioners
Mount these tensioners directly onto your chain drive. They have adjustable straps that take up slack and apply constant tension. Because they engage with the side plates instead of the rollers, they increase the life of your roller chain.
UHMW tensioners are stronger and more durable than PTFE tensioners.
Titanium tensioners stand up to harsh and dirty environments. They're stronger and more durable than plastic tensioners. And with a low coefficient of friction, they work with chain that has little or no lubrication.
