SPB V-belts

SPZ, SPA, SPB and SPC are the ISO narrow sections. At equal width they carry more power than a classical belt, and they run on smaller sheaves. The figure after the section letters is the datum length in millimeters.

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.
