Timing Belt

A timing belt is a precision power transmission component made from heat resistant rubber reinforced with fibers such as fiberglass or aramid. The belt typically has a thickness between 6 and 12 millimeters and a width between 20 and 35 millimeters, and it features HTD or STD tooth profiles. Tooth hardness ranges from 70 to 85 Shore A and the belt withstands temperatures from 90 to 120 degrees Celsius. The inner surface includes a low friction nylon coating that improves cyclic durability. This structure ensures synchronized motion between the crankshaft and camshaft.

A timing belt usually withstands tensile forces of 1500 to 3000 newtons and is manufactured with a length tolerance of less than 0.5 percent. Longitudinal reinforcement fibers provide dimensional stability at high rotational speeds and prevent tooth pitch deviation. The belt delivers consistent performance at operating speeds of 3000 to 6000 rpm. Many belts are produced using HNBR rubber to improve resistance to oil and ozone. The precise tooth design prevents slippage and reduces power transmission losses.
