564745R91 Drive Idler Pulley For Case-IH Combine

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.

Application Of Idler Pulley:

There are several types of idler pulleys that are commonly used in different applications:

Flat Idler Pulleys: Flat idler pulleys are the most basic type of idler pulley. They have a flat surface on which the band or chain runs and are usually used to guide and tension the band or chain in a straight line. They come in a variety of sizes and materials and can be mounted on a bracket or arm.

V-Belt Idler Pulleys: V-belt idler pulleys are designed to guide and tension V-belts in an application. They have a V-shaped groove that matches the profile of the V-belt and are commonly used in automotive engines, agricultural equipment, and industrial machinery. They come in a variety of sizes and materials and can be mounted on a bracket or arm.

Timing Belt Idler Pulleys: Timing belt idler pulleys are designed to guide and tension timing belts in an application. Their toothed surface matches the profile of the timing belt and is commonly used in automotive engines and industrial machinery. They come in a variety of sizes and materials and can be mounted on a bracket or arm.

Spring-Loaded Idler Pulleys: Spring-loaded idler pulleys are designed to automatically adjust the tension of the belt or chain in an application. They have a spring mechanism that allows them to move in response to changes in tension and are commonly used in car engines and industrial machinery. They come in a variety of sizes and materials and can be mounted on a bracket or arm.

Double Idler Pulleys: Double idler pulleys are designed to guide and tension two belts or chains in an application. They have two separate grooves or surfaces on which belts or chains run and are commonly used in agricultural equipment and industrial machinery. They come in a variety of sizes and materials and can be mounted on a bracket or arm.
