v belt size chart

The W211 PK ribbed belt is designed with multiple grooves along its length. This ribbed or serpentine design increases the surface area and improves grip on the pulleys it contacts. The belt is typically constructed from high-quality rubber, which may be reinforced with various materials to enhance durability and resistance to wear, heat, and environmental factors. As a result, these belts can efficiently transmit power to multiple components, including the alternator, air conditioning compressor, power steering pump, and water pump.

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.
