Materials Made for your Application Challenges.
Gates molded notch V-belts are exclusively constructed with EPDM, a high-performance synthetic rubber compound. Belts made with EPDM offer a 70% broader temperature range tolerance compared to other belts and resist hardening to avoid cracking. They meet The Rubber Manufacturers’ Association (RMA) standards for oil and heat resistance, as well as static conductivity.
A notch on your belt.
Gates designs molded notches in our belts to reduce the bending stress as the belt wraps around small diameter pulleys, thereby reducing the heat generated by rapid flexing to prevent premature belt failure. A relatively large, deep notch provides excellent flexibility for bending around pulleys by implementing the notch near the cord line.
