A Section V-Belts are the most widely used classical V-belt profile, featuring a 1/2" top width and 5/16" depth. Designed for light to medium industrial power transmission, A-section belts are found on fans, blowers, pumps, compressors, HVAC equipment, machine tools, and general industrial machinery.

A-section belts use inside circumference for part numbering. To convert from an outside measurement, subtract 2 inches. Example: OC 70" → 70 - 2 = A68. A-section belts are interchangeable with 4L FHP belts in many applications — both share the same 1/2" top width and fit the same sheaves.

We stock A-section V-belts from Diesel Belting, Gates, Continental ContiTech, Bando, Jason Industrial, and Megadyne in sizes from A21 through A180+.
