AA V-belts

AA, BB and CC double-V belts have a hexagonal cross-section and transmit power on both faces, which makes them the choice for serpentine drives with sheaves on either side of the belt.

The part number on the old belt is all we need to quote it. Worn off? Measure its top width and length, or photograph the sheaves and note their diameters and the center distance; from that we can tell which belt you need.

We manufacture the sheaves for these belts, from 1 to 18 grooves, plus specials to drawing.
