Komatsu High Quality Excavator Parts PC460-8 PC500-10 Undercarriage Spare Parts For Bottom Heat-treated Track Roller 208-30-00464
1. What is a track roller?
Supporting the bulldozer's full weight, enduring severe ground shocks, and generating >70% of operational resistance, track rollers are the undercarriage's critical load-bearing core. Each roller is subjected to a demanding 0.6 MPa (6 bar) high-pressure gas test, 60% beyond typical industry requirements, to ensure reliability in the toughest conditions. This key quality control step prevents oil leaks at their origin, resulting in assemblies validated for lifespans exceeding 3,000 hours despite constant immersion in highly abrasive media like mud and sand.
2. Engineering Excellence: Why Our Track Rollers Dominate Severe Conditions
✅ Military-Grade Sealing Integrity
Each roller undergoes rigorous 0.6 MPa (6 bar) high-pressure gas testing – 60% beyond industry standards – to guarantee zero-leak reliability in extreme conditions. This critical QC process eliminates oil seepage at the source through advanced sealing technology. Validated via accelerated wear simulations, the assemblies deliver >3,000-hour operational lifespans despite constant immersion in abrasive mixtures (e.g., silica-rich mud, granite slurry) and dynamic stresses from rock impacts. The result: field-proven resilience that slashes maintenance costs.
✅ Forged Alloy Armor Defense
Precision metallurgy for extreme environments:
-
Surface Shield: 60-65 HRC hardness → Crushes wear
-
Structural Core: 450MPa+ tensile strength → Defies impacts
-
Shaft Defense: Triple chrome plating → Outlasts corrosion
✅ Battle-Proven Load Capacity
Engineering breakthroughs eliminating failure modes:
✓ 30% optimized load distribution → Neutralizes stress concentrations
✓ Reinforced raceways/bearings → Prevents flange wear & bending
✓ Sustained cyclical load endurance → Slashes downtime, boosts longevity
