1. OEM-Grade Forged Material & High Hardness Heat Treatment
The PC200 track roller is manufactured with premium 50MnB alloy steel via one-piece forging technology, strictly complying with Komatsu's OEM material standards for excavator undercarriage parts. The whole wheel body undergoes professional quenching and tempering heat treatment, achieving a surface hardness of HRC56-62 with a deep hardened layer of 8-12mm, which far exceeds the industry basic standard of HRC52-58. This high-strength material and heat treatment combination endows the roller with exceptional wear, extrusion and impact resistance, perfectly adapting to harsh working conditions like mines, construction sites and muddy land with gravel and rock.
