Poly V-belts, also known as ribbed belts or multi-V belts, are a type of flat belt characterized by their slender, elongated ribbed structure. Unlike traditional V-belts, which have a triangular cross-section, Poly V-belts are designed with multiple parallel grooves that run along their length, enabling them to grip pulleys with enhanced efficiency. This design allows for a larger surface area contact between the belt and the pulley, leading to improved power transmission capabilities.

The 7PK belt belongs to the PK series of V-belts, characterized by its flat top, symmetrical angle, and a more extensive body that allows for enhanced load capacity. The 7 in 7PK designates the number of ribs or grooves present in the belt, which allows it to effectively handle greater tension and distribute the load evenly across its surface. This unique feature significantly contributes to its performance and longevity, especially in demanding environments.
