polyurethane timing belts

The primary function of a fan belt is to transfer rotational power from the engine's crankshaft to various engine accessories. This is done through a series of pulleys that the belt winds around, allowing multiple components to operate simultaneously. In modern vehicles, the serpentine belt design has largely replaced traditional V-belts due to its ability to drive multiple accessories with a single belt, which improves efficiency and reduces the weight of the engine compartment.

A poly belt, also known as a serpentine belt, is a continuous loop that drives multiple peripheral devices in an automobile's engine. This type of belt is made from a durable, flexible rubber compound and features several grooves that run along its length, allowing it to grip the various pulleys it interacts with. The 7PK 612 model specifically denotes the belt's dimensions, with the 7PK indicating that it has seven ribs, and 612 referring to its length in millimeters, approximately 612 mm.
