flat and v belt

A poly V belt, also known as a serpentine belt, is characterized by its multiple longitudinal ribs that provide increased surface contact and improved grip compared to traditional flat belts. The “135J6” designation denotes the specific dimensions and specifications of the belt. In this case, “135” refers to the belt’s length, while “J6” indicates the width and configuration. The poly V belt is designed to fit into a pulley system and is often used to drive multiple accessories in engines, including alternators, power steering pumps, and air conditioning compressors.

An endless flat drive belt is a continuous loop made from flexible materials, designed to transmit power between pulleys located at varying distances. Unlike traditional belts that often feature a textured surface or teeth for grip, flat belts rely on friction between the belt surface and the pulleys to facilitate movement. The endless feature indicates that the belt has no joints or seams, reducing the risk of wear and breakdown while ensuring a smooth operation.
