The chain with excellent wear resistance and minimal friction losses.
The simplex and duplex bush chain with a 3/8" pitch was designed for timing drives with more exacting requirements such as diesel engines.
Owing to their small pitch, bush chains with a pitch of 7 or 8 mm cut the weight and consequently reduce the centrifugal forces and impact speed. They are therefore particularly suited to high-speed drives (e.g. mass balancing drives).
