    3/BX158 TRI-POWER POWERBAND

    Product # 90983158

    Built for superior performance on heavy duty classical cross-section drives. The raw edge, Ethylene Elastomer construction and special notch design makes the Tri-Power belt especially suited for small diameter pulleys and back side idler drives.

    • 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. 15% capacity increase over wrapped belts.
    • Notches molded into the belt during manufacturing increase flexibility, making this belt well suited for drives with smaller diameter sheaves.
    • Suitable for all industrial applications, particularly where small or sub-minimal sheave diameters are required.
    • Meets ARPM/RMA IP-3-2 oil and heat resistant standards and IP-3-3 static conductivity requirements. REACH and RoHS 2 compliant.

    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.
