flat rubber belt material

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.

Manufactured primarily from durable rubber compounds, these belts are often reinforced with synthetic fibers to withstand the rigors of temperature, humidity, and mechanical wear. Advanced materials used in the production of rubber ribbed belts can greatly enhance their longevity and resistance to cracking, hardening, or stretching. Many modern belts also incorporate special coatings or additives to further enhance their performance and lifespan.
