Poly rib V-belts, also known as multi-ribbed V-belts or serpentine belts, are a type of power transmission belt that features multiple ribs or grooves on the inner surface of the belt. These ribs run parallel to the length of the belt and provide increased flexibility, traction, and surface area contact with the pulleys, allowing for efficient power transmission.
Poly rib V-belts are commonly used in automotive engines, HVAC systems, industrial machinery, and other applications where multiple pulleys need to be driven simultaneously. The multiple ribs on the belt allow for better grip and traction on the pulleys, reducing slippage and improving power transmission efficiency.
These belts are typically made from a combination of rubber and polyester materials, which provide durability, flexibility, and resistance to wear and tear. The ribbed design of the belt helps distribute the load evenly across the belt surface, reducing stress and extending the service life of the belt.
