Product Function and Working Principle of Doosan DH220 Track Roller
The track roller on the Doosan DH220 excavator supports the weight of the machine and guides the track chain along the undercarriage frame. By evenly distributing the load and reducing friction between the track chain and the ground, the roller enables smooth, stable movement across rough terrains. This component is critical for maintaining machine balance and minimizing wear on other undercarriage parts during mining, construction, and heavy excavation projects.
High-Quality Materials and Advanced Manufacturing Process
Our DH220 track rollers are made from premium 45# carbon steel and high-strength alloy steel bushings like 40Cr or 42CrMo, which undergo strict heat treatment processes. The roller surface is induction hardened to achieve a hardness of HRC52-58, providing excellent wear resistance and impact strength. This material combination ensures outstanding durability under harsh working environments such as mining sites and earthmoving applications.
Precision Forging and Assembly Techniques for DH220 Track Roller
Using advanced forging technology, the DH220 track roller achieves uniform metal density and enhanced structural integrity. The roller body and shaft are forged in a single piece or assembled with tightly fitted bushings, reducing the risk of failure. After forging, precision machining ensures tight dimensional tolerances, guaranteeing proper fitment with Doosan DH220 undercarriage systems. Quality assembly processes and oil sealing further protect internal components from dirt and moisture.
