Belt Cross Section

V-Belt Cross Section

A V-belt cross section is the belt profile and is consistent across manufacturers to ensure compatibility with standard pulleys (sheaves) in a power transmission drive. Some cross sections are for individual belts; some are for groups of belts that perform as one belt. Common cross sections are A, B, C, D, E, 3V, 5V, and 8V for single profile belts, and J, L, and M for ribbed (also called V-ribbed) profiles.
