An idler roller conveyor is a type of material handling system used to move products from one place to another. It consists of a series of rollers that are supported by frames, called idler rollers, which provide a surface for the product to move along. The idler rollers are mounted on bearings and are used to support and guide the product as it moves along the conveyor. Unlike powered roller conveyors, idler roller conveyors rely on gravity or manual force to move the product. They are commonly used in light-duty material handling applications such as packaging, assembly, and storage.
