    POLY CHAIN®:
    THE MOST ADVANCED BELT IN THE WORLD

    Quiet, lightweight, and clean-running, the hard-wearing Gates® Poly Chain family is renowned for its extraordinary strength and load-carrying capacity. Incorporating either aramid or Gates patented carbon fiber tensile cords for minimal stretch, Poly Chain belts have a curvilinear tooth profile that increases shear strength. A nonslip nylon tooth facing reduces friction and eliminates the need for lubrication.

    POLY CHAIN® CARBON™ VOLT™ 

    The first synchronous belt system engineered to prevent electrostatic discharge, Poly Chain Carbon Volt keeps your drives safe in hazardous environments. Built with carbon fiber tensile cords for strength and compactness, and a durable polyurethane body for chemical and abrasion resistance, it delivers quiet, maintenance-free performance across a wide range of applications - even where static sparks can’t be tolerated.

    POWERGRIP™ GT™4

    The latest in industrial rubber synchronous technology from Gates, PowerGrip GT4 is the ethylene elastomer high-torque belt that drives the highest power-carrying capacity of any belt in its class. It elevates efficiency in narrower drives. And with no lubrication or re-tensioning necessary, there’s no need for maintenance — improving your uptime and productivity.

    POWERGRIP GT™2 TWIN POWER™

    Gates PowerGrip GT2 Twin Power belts are double-sided, transmitting 100% of the maximum rated load from either side, and enabling synchronisation from both drive surfaces. The large tooth profile increases performance capacity, handles high speeds, and withstands extreme temperatures from -22°F to 212°F (-30°C to 100°C).

    FORESTRY & LUMBER

     

    Unlike roller chain, Gates Poly Chain belts need no maintenance, re-tensioning, or lubrication. Durable and incredibly strong, they’re ideal for forestry and sawmill applications such as debarkers, saws, conveyors, planers, and stackers. The nonslip design maintains speed and saves energy, and Poly Chain withstands wide-ranging temperatures.

    AGRICULTURE

     

    From field to processing line, Gates synchronous belts power the machines that keep your farm running. Ideal for equipment such as potato sorters, graders, harvesters, and conveyors, our belts deliver consistent performance in dusty, dirty, and high-load environments. Built to resist debris, shock loads, and small tensioner forces, Gates solutions help you minimize downtime and maximize throughput every season.
