    High-Capacity Narrow-Wedge Cogged V-Belts

    Image of Product. Front orientation. V-Belts. High-Capacity Narrow-Wedge Cogged V-Belts.
    A narrow belt profile transmits up to three times the horsepower of standard cogged V-belts for use on heavy duty drives with shock loads. Notches increase flexibility for bending around small-diameter pulleys and dissipate heat for a long service life.
