    Multi-Speed Belt

    Gates Multi-Speed belt provides top performance on variable speed drives. It adjusts itself to the pulley groove without difficulty, providing a wide range of speeds and speed ratios. In addition to the standard Multi-Speed belt line, special sizes (top width, thickness and angle) are available on request.

    • The notches ensure maximum heat dispersion, considerably decreasing running temperatures.
    • Strong transverse rigidity offers high resistance to distortion of the belt in the pulley.
    • Even load distribution and wear reduction.


    In today's applications, power transmission systems do more than operate at constant speeds with constant outputs. Our customers increasingly need variable speed systems to regulate the speed and rotational force, or output torque, of critical mechanical equipment. Our Multi-Speed belts are engineered for efficiency, energy savings, and increased productivity at a wide range of speeds and speed ratios.

    Features and Benefits

    • Uniform composition and thickness of the undercord ensure smooth and silent running.
    • Engineered notch contour increases flexibility.
    • Temperature Range: -30°C up to +60°C.
    • High load-carrying capacity.
    • Smooth machine operation.
    • Exceptionally long belt life.
    • Maximum speed adjustment.


    Gates® designs moulded notches in our belts to reduce the bending stress as the belt wraps around small diameter pulleys, thereby reducing the heat generated by rapid flexing to prevent premature belt failure. A relatively large, deep notch provides excellent flexibility for bending around pulleys by implementing the notch near the cord line.
