    Features and Benefits

    • Excellent adhesion of tensile cords and polyurethane compound leads to high fatigue resistance and long belt life.
    • Small cross-section meets special application needs such as high shaft speeds, small drive package size and smooth running requirements.
    • The 60° angle provides more undercord support to the tensile section and distributes the load more evenly.
    • Ribs relieve bending stress on small pulleys and provide lateral rigidity.
    • Long belt life on small pulleys and compact drives.
    • The precise casting method eliminates overlaps and layers.
    • High performance and smooth running for precision applications.
    • Avoids vibrations when subjected to shock loads.
    • Joined Belt construction improves stability.
    • Greater shaft speeds, up to 30,000 rpm.
    • Cost savings and design freedom.
