Double V-belts are primarily used in serpentine drive systems, where the belt needs to operate in a reversible direction or engage multiple pulleys that face different directions.
Just like classical V-belts, double V-belts come in standardized sizes. Double-section belts are typically labeled AA, BB, CC, DD, EE (instead of A, B, C, etc.), where the extra A, B, C, etc., indicates that the belt works on both sides.
| Belt Section | Top Width (mm) | Height (mm) | Angle (°) | Common Applications |
|---|---|---|---|---|
| AA | 13 mm (1/2″) | 10 mm | 40° | Light-duty serpentine drives |
| BB | 17 mm (21/32″) | 13 mm | 40° | Medium industrial applications |
| CC | 22 mm (7/8″) | 17 mm | 40° | Heavy-duty industrial applications |
| DD | 32 mm (1-1/4″) | 25 mm | 40° | Large machinery, high-torque applications |
| EE | 38 mm (1-1/2″) | 30 mm | 40° | Extra-heavy-duty applications |
