Rubber Timing Belt

Rubber timing belt provide high precision transmission system, due to its structure, raw materials, production system and quality.

Give properties similar to transmission gears and chains, and having no metal contact, avoid noise and friction wear.

Its structure is composed of glass fiber tensile cord which gives high breaking load, outstanding fatigue resistance and zero stretch.

The teeth are constructed by special rubber compounds, and coated nylon fabric to protect the tooth surface with self-lubrication.
