Komatsu PC200-6 Excavator Undercarriage Carrier Roller (Top Roller) - OEM Replacement for Mining
As a professional OEM replacement carrier roller (also known as top roller) for Komatsu PC200-6 excavators, this undercarriage component is specifically engineered to meet the rigorous demands of harsh mining, construction and heavy-duty working environments. As a critical part of the PC200-6's undercarriage system, the carrier roller plays a vital role in supporting the upper part of the track, preventing track sagging and ensuring stable track operation—directly affecting the excavator's overall efficiency and service life.
Crafted from high-quality 40Mn2 or 50Mn alloy steel (optional), this carrier roller is manufactured via precision forging process, combined with quenching and tempering heat treatment, to achieve superior structural density, enhanced tensile strength and exceptional wear resistance. It effectively overcomes the challenges of rock impact, gravel abrasion and uneven terrain that often cause premature damage to conventional undercarriage parts.
Strictly adhering to PC200-6 OEM dimensional specifications and undercarriage geometry, this carrier roller enables direct, modification-free installation, ensuring tight fit with the track and stable operation. Equipped with high-chromium high-molybdenum floating seals and O-type NBR oil seals, it effectively blocks contaminants from entering the internal components, reduces wear on bearings and bushings, and extends service life even in harsh working conditions.
