RABS Series Flanged Idler Pulley

An idler pulley is a common component in engines and machines that maintain tension and route belts or chains. They usually consist of a pulley wheel mounted on a fixed shaft that does not transmit any power but can rotate freely. The idler’s main function is to act as a guide for the belt or chain, ensuring that it follows the correct path and maintains the proper tension. Without an idler, the belt or chain may become loose or misaligned, resulting in reduced efficiency and even damage to the machine. Idlers are commonly used in vehicles, such as cars and trucks, as well as heavy machinery, such as construction equipment and industrial machinery.
