Timing belts play an important role in controlling the operation of pistons. They are also responsible for synchronizing the rotational motion of the crankshaft pulley and the camshaft. Depending on the application, timing belts can be made of different materials.

A rubber open ended timing belt is a good alternative to a chain. It can be used for a variety of applications, especially in the automotive industry. Moreover, it is ideal for applications that require linear motion. For example, CNC machines, robotic machines, textile machinery and other electronic equipment.

Rubber open end timing belts have excellent positioning accuracy on reverse drives. These belts are available in various materials, including polyurethane, thermoplastic polyurethane and extruded polyurethane. There are also variants with a pair of pulleys for the camshaft.

Polyurethane timing belts have a high spring rate. The tooth shear strength of these belts is also good. In addition, they are dimensionally stable. Their excellent wear resistance and temperature resistance make them a good choice for linear drive systems.
Neoprene is also a popular material for timing belts. It has good wear characteristics and is easy to clean. Besides, it is designed to hold the tooth profile accurately.

The back side cushion is also a feature of this type of timing belt. During transmission, it helps reduce the amount of dust that sticks to the teeth.
Synchronous belts should avoid contact with water and chemicals. Especially for industrial applications, they should be able to transmit high torque.
