3V V-belts

3V, 5V and 8V are the narrow sections of the American standard. The leading digit gives the section width in eighths of an inch; the figure after it gives the effective length in tenths of an inch.

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.
