Doosan DX420 Bulldozer OEM Carrier Roller 50Mn Alloy Steel Heat Treated

The roller is a crucial component of belt conveyors, supporting both the conveyor belt and material weight. Accounting for 35% of total conveyor cost and generating over 70% of resistance, roller quality is paramount. Available in steel or plastic construction.

Our track and carrier rollers utilize materials including 40Mn2, 40MnB, and 50Mn alloy steel, selected based on working conditions. The rollers undergo normalization with precision forging before complete heat treatment, achieving surface hardness of HRC52-60 with a hardened layer depth of 7-10mm (HRC45). This ensures exceptional durability with high impact resistance and surface wear resistance.

Featuring high-quality floating seals and advanced lubrication systems, our rollers perform reliably in extreme conditions from -45°C to 120°C, requiring minimal maintenance.
