Frequently Asked Questions
A Hex Belt, or Double V-Belt, has a hexagonal cross-section: the top and the bottom are both V-shaped working faces, so either side of the belt can drive a pulley. It is designed for reverse-bend serpentine drives, where the belt runs around several pulleys in one plane and bends in both directions.
