Rollers are indispensable elements within belt conveyor systems. They exist in a plethora of types and are utilized in substantial numbers. Their fundamental tasks involve providing support to not only the conveyor belt but also the weight of the materials being conveyed. Notably, rollers constitute around 35% of the overall cost of a belt conveyor installation. Furthermore, during the operation of the system, they create more than 70% of the operational resistance, which highlights the extreme significance of the quality of rollers. In contemporary roller designs, two main materials are commonly used for construction: steel and plastic.
