Poly V belts, also referred to as serpentine belts, consist of multiple V-shaped grooves running parallel along their length. This unique design allows for a higher surface area contact, which leads to better power transmission and efficiency compared to traditional V belts. Poly V belts are specifically engineered to handle high-speed operations while maintaining a compact format, which is crucial in modern machinery and vehicles that strive for space efficiency and weight reduction.
