When you need to drive pulleys on both sides of a belt, standard V-belts won’t work — they only have one wedge surface. Hexagonal V-belts (also called double V-belts or hex belts) solve this with a symmetrical cross-section that engages pulleys on both the top and bottom surfaces.
We manufacture hexagonal V-belts for agricultural equipment, industrial machinery, and specialty applications where serpentine routing or reverse-bend drives are required. Our IATF 16949 certified facility produces these belts to the same quality standards as our automotive lines.

The symmetrical hexagonal cross-section allows the belt to engage V-pulleys on both sides. This enables complex drive layouts where pulleys rotate in opposite directions or where the belt must wrap around multiple shafts.
Standard V-belts can only bend in one direction (around the inner surface). Hexagonal belts can bend both ways, allowing serpentine routing through multiple pulleys.
Farm equipment often requires driving multiple implements from a single power source, with shafts rotating in different directions. Hexagonal belts are standard equipment on many combine harvesters, tractors, and other agricultural machinery.
| Section | Top Width | Thickness | Equivalent Single V | Typical Applications |
|---|---|---|---|---|
| AA | 13mm | 10mm | A | Light duty, small equipment |
| BB | 17mm | 14mm | B | Medium duty, most common |
| CC | 22mm | 17mm | C | Heavy duty agricultural |
| DD | 32mm | 25mm | D | Extra heavy duty |
Standard for agricultural applications. Excellent elasticity and tear resistance for shock-load environments.
Better oil resistance for industrial applications where contamination is a concern.
Heat-resistant option for high-temperature or outdoor applications with significant sun exposure.
Hexagonal belts must be symmetrical — both wedge surfaces need identical geometry for proper pulley engagement. Our IATF 16949 certified quality system ensures:
Only if the drive requires dual-sided engagement. If the drive only uses one side of the belt, a standard V-belt is more cost-effective and will perform identically.
Look at the cross-section — hexagonal belts have the same wedge shape on both top and bottom. The designation will typically include “AA”, “BB”, “CC”, or “DD” (doubled letters indicating double-sided).
