Komatsu PC600 Excavator Undercarriage Spare Parts - Professional
Heat-treated Track Bottom Roller 9109493
1. What is a track roller?
Track rollers serve as the undercarriage’s load-bearing backbone, tasked with supporting the bulldozer’s full weight, absorbing
severe ground shocks, and contributing to over 70% of operational resistance—a non-negotiable role in machinery performance.
For track and carrier rollers, materials like 40Mn2,40MnB,50Mn are selected based on working conditions. Through precision
forging and subsequent heat treatment, the rollers achieve HRC52-60 surface hardness and a 7-10mm hardened layer depth (HRC45), ensuring high impact resistance and wear durability on their
contact surfaces. Equipped with high-quality floating seals and a
reliable lubrication system, they operate seamlessly in extreme
climates ranging from -45℃~120℃ with minimal maintenance requirements.
Our Track Rollers feature a unique welding-before-CNC-machining
process on vertical lathes, eliminating concentricity errors and
significantly reducing rapid wear issues. This craftsmanship
ensures superior operational stability and extends the service life of the products, delivering unmatched quality in heavy-duty applications.
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
