Leaf chains are designed of leaf chain china interlaced plates held collectively by rivet pins. They are built with the same high degree of precision as our roller chains. Leaf chains are used for applications that require strong flexible linkage for transmitting movement or lift. Specifically selected steel and unique heat therapy assures high durability and strength. The first amount or numbers in leaf chains identifies the chain pitch, the last two figures identify the chain’s lacing. New applications should use BL series leaf chains
