A ribbed belt is a flexible belt made from rubber or composite material, featuring ribs that run along its inner surface. These ribs grip the pulleys, providing the necessary traction to transfer power from the engine's crankshaft to various engine accessories. Unlike older V-belts, which were designed to drive a single accessory, the ribbed belt can handle multiple components simultaneously. This design not only simplifies engine layout but also improves performance and efficiency.

The poly V belt, often referred to as a multi-ribbed or flat belt, is designed with multiple ribs or grooves running parallel to its length. This configuration allows for a greater surface area to engage with the pulleys, leading to enhanced grip and power transmission. The J section designation refers to the specific profile of the belt, which is tailored to fit a range of applications that require high performance and efficiency. The unique design not only minimizes slipping but also reduces the overall width of the belt, making it ideal for compact spaces.
