A belt and pulley system is characterized by two or more pulleys in common to a belt. This allows for mechanical power, torque, and speed to be transmitted across axles. If the pulleys are of differing diameters, a mechanical advantage is realized.
Belts are made of highly durable rubber compound and a special tension member, which ensures long service life, high efficiency, high temperature and chemical resistance.
