1. What is a roller?
The roller, a crucial component within engineering machinery chassis conveyors, exhibits diversity in types and substantial quantities, effectively supporting the conveyor belt and the load of transported materials. Representing 35% of the overall conveyor's cost, it generates over 70% of the resistance encountered. Hence, the quality of the roller is of utmost importance. These rollers are manufactured using two primary materials: steel and plastic.
