ansi standard attachment bicycle roller chains 

Leaf Chain is the most simple of steel chains, consisting only of link plates and pins. This chain generally has greater tensile strength than roller chains and runs over sheaves rather than Sprockets. They are suitable for hanging, balancing or motion transmitting applications. Leaf chains are often used as counterweight chains for machine tools, elevator and oven doors, fork lift truck masts, spinning frames and similar lifting or balancing applications.

Plates are connected by pins and hold the tension loaded on the chain.

AL Type
Plate configuration and thickness are the same as ANSI G7 roller chain. Pin diameter is almost the same as ANSI G7 roller chain.

BL Type
BL Series leaf chains consist of link plates which are thicker and larger in contour than the AL Series link plates of the same pitch. The link plates have the same thickness as the link plates of the next larger pitch size in ANSI G7 roller chains. The pins have the same diameter as those of ANSI G7 roller chains of the next larger pitch.
