Classic-section raw edge GUFERO® vee-belts are vee-belts with internal gearing and are employed for the transmission of high power and revolutions. Classic-section raw edge vee-belts are used in all types of machines with higher loads. They are used as an alternative to wrapped vee-belts as a way to improve service life and reduce the number of vee-belts in sets. These vee-belts are widely used in all fields of mechanical engineering, starting with precision machinery up to heavy machinery. The advantages of classic-section raw edge vee-belts include the aforementioned transmission of high power and revolutions and a high circumferential speed of up to 50 m/s. The temperature resistance of classic-section raw edge vee-belts is from -30 °C to +90 °C.
