The Industry's Best.

With patented, carbon tensile cord design for high-torque, low-speed drives, Gates® engineers were the first in the world to incorporate a high fatigue-resisting carbon fiber tensile cord into the belt, which is made of a new polyurethane compound. Consequently, Poly Chain® GT™ Carbon™ quickly became the most powerful line of synchronous belts on the market, providing a maintenance-free, energy saving, and environmentally friendly operation, offering an excellent alternative to roller chain and gear drives.
