Gates Micro-V Belts feature an exclusive truncated rib profile that makes it more flexible than a conventional V-ribbed belt, especially on extra-high speed, small-diameter sheave drives. Also, the shortened rib profile keeps the multi-ribbed belt from bottoming out, helps it tolerate debris in grooves, and reduces heat build-up. The belt is ideally suited for most multi-shaft, serpentine, backside idler and V-flat drives.
