    Tri-Power® PowerBand® Belts

    With a proprietary construction, Gates Tri-Power® PowerBand® belt has a superior combination of flex and load carrying capacity. This belt is engineered to transmit more horsepower than the classic cross sections in the same amount of drive space.

    • Belt Edge is machined for even sheave groove contact, resulting in smoother running, less slip and wear.
    • Flex-Bonded Cords are strongly forged to the belt body, resulting in equal load distribution and absorption of bending stress without cord deterioration.
    • Notches molded into the belt during manufacturing increase flexibility, making this belt well suited for drives with smaller diameter sheaves.
    • Patented Ethylene Material construction provides -51°C to +121°C (-60°F to +250°F) temperature range to resist belt cracking.
    • 15% capacity increase over wrapped belts.

    Perfect Belts for Imperfect Conditions.

    Over time, belts fail from heat cracks, stretching, or excessive wear. Belt re-tensioning and replacement leads to downtime, inefficiency, and loss of productivity. Our molded notch V-belts, including the Tri-Power belt line, offer a patented, new ethylene construction to keep your operations running when other belts fail.

    Longer Life at Extreme Temperatures.

    Ethylene rubber material (EPDM) resists hardening to avoid cracking with 88% broader temperature range compared to other belt materials, with a range from -51°C to +121°C (-60°F to +250°F). Gates® Tri-Power PowerBand belts meet ARPM/RMA standards for oil and heat resistance as well as static conductivity.
