Their design enables them to pass around smaller diameter sprockets thus demanding less space than the link chain design.įor light duty automobile engines, the roller chain may be of a single row configuration (like the bicycle chain). Roller chains are much like bicycle chains in appearance but are larger, far stronger and more durable. For this reason, this design is sometimes referred to as a ‘silent chain’. The link shape is intended to smoothly engage each sprocket. Each link’s shape conforms to the driving surfaces of both the crankshaft driving sprocket and camshaft driven sprocket. Link chains consist of many precision links fabricated of flat hardened alloy steel held together by pressed pins. These designs have their origins back into the late 19th century. Two types of timing chains are in service today, the link chain and the roller chain.
