a serpentine belt

The PK 5PK belt is part of the PK belt family, characterized by its trapezoidal tooth profile and its capability to provide high power transmission efficiency. The 5PK designation refers to the specific size and configuration of the belt—namely, that it has five ribs or teeth running along its length. This multi-ribbed design offers several advantages over traditional single-ribbed belts, making it a preferred choice for many manufacturers and engineers.

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.
