Hitachi EX35 Excavator Track Bottom Roller Alloy Steel 2-Year Warranty

The roller is a vital component of belt conveyors, available in diverse types and large quantities. Its core function is to support both the conveyor belt and the weight of transported materials. Rollers account for 35% of a belt conveyor's total cost while generating over 70% of the system's operational resistance, making their quality critical to overall performance and efficiency.

Track rollers use premium materials including 40Mn2, 40MnB, and 50Mn, selected based on specific working conditions. Each roller undergoes precision forging and normalization, followed by overall heat treatment. This process achieves a surface hardness of HRC52-60 and a hardened layer depth of over 7-10mm (HRC45), ensuring superior durability along with high impact resistance and strong surface wear resistance on the rollers' contact surfaces.

Equipped with high-quality floating seals and a reliable lubricating system, these rollers adapt seamlessly to diverse climates and temperatures. Both track and carrier rollers perform stably under severe working conditions or extreme climates ranging from -45℃ to 120℃, while remaining maintenance-free.
