An idler wheel is a mechanical component that is used in various types of machinery and systems. Its primary function is to guide or support a moving part, such as a belt or a chain, without providing drive power. Idler wheels help to maintain proper tension in a belt-driven system, reducing slack and ensuring smooth operation. They can be found in applications like conveyor systems, printers, automotive engines, and other machinery where belts or chains are utilized.
