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.
2. Track Rollers Excavator Advantages / Features
Track rollers utilize materials such as 40Mn2, 40MnB, and 50Mn, carefully selected based on working conditions. Each roller
undergoes precision forging and normalization before overall heat treatment, achieving a surface hardness of HRC52-60 with a hardened layer depth exceeding 7-10mm (HRC45). This process ensures exceptional durability, delivering high impact resistance and superior surface wear resistance on the contact surfaces.
Fitted with high-quality floating seals and a robust lubricating system, these rollers adapt seamlessly to diverse climates and
temperatures. Both track and carrier rollers operate reliably in severe conditions or extreme climates ranging from -45℃ to 120℃, all while requiring zero maintenance.
