製品説明

We produceTrack Roller for Komatsu PC400 208-30-00210 specifically for heavy-duty Komatsu PC400 excavators operating in harsh working environments such as mining sites, quarries, and large-scale earthmoving projects.

At Quanzhou Qiansheng Heavy Industry Machinery Co., Ltd., we focus on real working conditions, not lab theory. Every roller is designed based on long-term field feedback from construction fleets and machinery dealers who operate under continuous load and impact.

Key Featuresand Engineering Strength

1. Heavy Load Bearing Structure

The roller body is forged from high-strength alloy steel (40Mn2 / 50Mn), ensuring strong resistance against deformation under continuous 40-ton machine pressure. This structure is proven in long-hour mining operations where undercarriage stress is constant.

2. Deep Heat Treatment for Wear Resistance

Through medium-frequency induction hardening, the tread surface reaches high hardness levels with deep hardened layers. This allows the PC400 Bottom Track Roller to withstand abrasive materials like granite, gravel, and mixed rock soil without premature wear.

3. Sealing System for Harsh Conditions

We use heavy-duty floating oil seals combined with precision bushings. This structure prevents mud, water, and dust intrusion, maintaining stable lubrication even in long continuous operations.

4. OEM-Level Fit Accuracy

Each unit is machined according to original Komatsu specifications. Installation is direct replacement with no modification required, reducing machine downtime during maintenance.
