A roller conveyor and a belt conveyor share a lot of their underlying mechanism. However, the lack of a belt in the former is what distinguishes it from the latter.

The rollers are generally cylindrical tubes fitted inside a steel or metal frame. Conveyor rollers are made of different materials according to their purpose. Some rollers are made of stainless steel and are also corrosion resistant. Rollers used in printing, paper processing and metal rolling industries need a gripping surface come with a rubber coating which increases the grip. Rollers made of plastic are also suitable for lightweight items. Zinc plated tubes are used for grooved conveyor rollers.

There are also different types of rollers for different applications. Friction driven conveyor rollers comes with nylon sprockets do to the job.
