1. What is a roller?

Cylindrical elements are indispensable components of conveyor systems—available in various models and readily supplied in abundant quantities, they reliably bear the combined load of the conveyor belt and the materials it transports. Their significance is underscored by two critical metrics: they account for 35% of a conveyor system’s total cost and generate over 70% of operational friction, making their quality non-negotiable. These elements are crafted from two primary material categories: metallic and polymeric.
