Sheaves for A section belts

Z, A, B, C, D and E are the classical sections: general-purpose V-belts that drive motors, pumps, fans and compressors. In the part number, the letter identifies the section and the digits after it give the length.

For a quote, measure the outside diameter and count the grooves; the part number of the belt it runs tells us the section. Specials with more grooves or other dimensions are manufactured to your drawings.
