Two re-engineered synchronous belt and sprocket systems from Gates provide overall low-cost-per-motor-horsepower savings for the life of the drive.

Gates Poly Chain® GT® 2 is ideally suited for low-speed (less than 500 rpm), high torque synchronous drives up to 1,200 hp. As a replacement for roller chain and rubber synchronous belt systems, it will reduce lifetime system costs by providing space, weight and maintenance savings.

Special construction features include a polyurethane body for abrasion and chemical resistance, and superior adhesion to the aramid fiber tensile cords. The tensile cords provide excellent flex fatigue life and high resistance to shock and surge loads. Nylon facing gives strength and durability to the belt teeth.

When combined with the compact Taper-Lock® sprockets/bushings, Poly Chain GT2 sprocket/bushing systems use less space than conventional sprockets and sheaves. In comparison with most competitive drives (roller chain or rubber), Poly Chain GT2 belt drives are as little as one-half the width and 50 percent lighter. Yet, they can deliver over five times more horsepower than standard rubber synchronous systems in the same space.

For high-speed, high-horsepower and accurate synchronization, Gates has developed the PowerGrip® GT®2 drive system for applications over 500 rpm.

Compared to similar first generation rubber synchronization belts, PowerGrip GT2 belts will transmit up to 200 percent more horsepower by using a narrower belt size on a smaller, more compact and energy efficient drive system, with no sacrifice in service life.

A fiberglass tensile member provides high strength, excellent flex life and high resistance to elongation. The belt's deep tooth design increases the contact area with the sprocket which provides smooth meshing, accurate registration, resistance to ratcheting, less vibration and reduced noise. The nylon facing on the modified curvilinear teeth gives increased protection and a low coefficient of friction for long service life.

Gates Power Grip GT2 drive systems feature Taper-Lock sprockets that have been specially designed to handle the new increased belt power ratings. The sprockets utilize Taper-Lock bushings. Their compact design allows narrow sprocket hubs for compact drive systems.
