374-8495 12PK Serpentine Belt
Cat® 5.71 mm Thick Rubber Fan Drive Pulley 12PK Serpentine Belt
Description
The serpentine belt is also known as an auxiliary drive belt, fan drive belt, and drive belt. The belt is long and winds through multiple pulleys. 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.
Features
- The effective length of the belt is 1505 ± 6 mm.
- Made of flexible materials, such as rubber or synthetic polymers, so it can bend and coil.
- Wear resistant.
- Provides 12 reinforcing ribs for better grip and reduced slippage.
Applications
The serpentine belt is used for the pulley in the fan drive in the engine.
