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