    BIG POWER FOR SMALL SPACES.

    Polyflex™ Belts were specially designed to transmit maximum power for a variety of small precision v-belt drive applications. The belt's ribs are designed to reduce bending stress on miniaturized drive components, while their 60° angle construction provides added support for even load distribution. This enable their use in high-performance, precision applications, accommodating shaft speeds in excess of 10,000 rpm.

    Features and Benefits

    • The 60° angle results in better support of the tensile section, and provides a more even load distribution.
    • Design freedom and space savings which are not possible with conventional rubber construction belts.
    • Ribbed backing provides greater lateral stability and relieves bending stress.
    • Polyurethane is extremely resistant to heat, chemicals and oil.
    • Low maintenance cost as belt needs less re-tensioning.
    • Improves adhesion to the tensile cords.
    • Long belt life on compact drives.

    A MATERIAL DIFFERENCE.

    Every Gates power transmission product is made at the leading edge of material science and manufacturing processes. Gates® Polyflex™ Belts are precision cast, using our own proprietary process that forms the belt in a seamless, single layer. Their HDPE compound construction provides material properties that combine strength, flexibility, and high temperature tolerance. The result is a precision application belt that provides exceptional load-carrying capacity, application versatility, and durability.
