    3M300 POLYFLEX

    Product # 89010300

    Developed by Gates and produced to patented manufacturing processes, these belts provide more load-carrying capacity at higher speeds to small multiple V-belt precision drives. This results in significant cost savings and improved design freedom.

    • High Modulus Polyurethane compound resists fatigue, wear, ozone and most environmental conditions. It also improves adhesion to the tensile cords.
    • Precise casting method eliminates layers and overlaps for smooth running and low vibration.
    • Ribbed backing provides greater lateral stability and relieves bending stress.
    • Unique 60° angle polyurethane construction results in better support of the tensile section that transmits a more even load distribution at higher speeds in less space than conventional v-belts.
    • Recommended for use on bench type milling machines, lathe drives, woodworking and metalworking machine spindle drives, computer peripheral equipment, small blowers, etc. Available on demand as matched sets.

    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.
