Description
The serpentine belt is also known as an auxiliary drive belt, fan drive belt, and drive belt. The belt can pass over more than three pulleys with a wrap angle large enough to avoid slippage, including an idler pulley that presses against the back of the belt, forcing the belt into a serpentine shape. The belt is long and winds through multiple pulleys.
Features
- Wear resistant.
- Provides 9 reinforcing ribs for better grip and reduced slippage.
- The effective length of the belt is 1540 ± 6 mm.
- Made of flexible materials, such as rubber or synthetic polymers, so it can bend and coil.
- Uses Orion Rib compound, a carbon black rubber that helps achieve a good balance of wear resistance.
Applications
The serpentine belt is used in accessory drives connected to various components, such as the alternator and fan drive with idler pulleys.
