molded ribbed poly v belts

A tensioner belt pulley is typically constructed from durable materials such as metal or high-grade plastic, designed to withstand the high temperatures and stresses present in an engine environment. The pulley is mounted on a pivot arm, allowing it to move as the belt tension changes. Most modern tensioners are equipped with a spring mechanism that automatically adjusts the tension on the belt, providing a consistent and precise amount of tension regardless of engine speed or load.

There are primarily two types of belts used in modern vehicles V-belts and serpentine belts. V-belts were once the standard in older car models, characterized by their V-shaped cross-section, which allows better grip on the pulleys. However, the serpentine belt has gained prominence due to its efficiency and compact design. A serpentine belt is a single, continuous belt that can drive multiple components, which reduces weight and space in the engine compartment.
