interference engine timing belt

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.

V-belts, named for their distinctive V shape, have a trapezoidal cross-section. This design allows them to fit snugly into matching grooves on pulleys, providing a higher coefficient of friction and enhancing grip during operation. The V-shape also allows for angular misalignment, which can occur in some machinery setups. Typically made from rubber, V-belts may also contain fabric and steel reinforcements to improve durability and flexibility.
