Product Description
Heavy-Duty PC200 Track Roller for Excavator Undercarriage Replacement
Are you looking to reduce your heavy equipment's maintenance costs and unexpected fleet downtime? Our premium PC200 Track Roller (also known as Bottom Roller or Lower Roller) is specifically engineered to withstand extreme loads and abrasive working environments. Ideal for heavy-duty mining and rugged construction sectors, this roller ensures your crawler machinery operates at peak efficiency.
Advanced Technical & Manufacturing Advantages
- Premium Forged 40Mn2 Steel: We utilize genuine, high-density 40Mn2 steel for forging. Through precise induction heat treatment, the surface hardness reaches HRC 50-55, providing exceptional wear resistance and preventing shell cracking under severe impacts.
- Japanese Friction Welding Technology: Manufactured using advanced friction welding tech imported from Japan to achieve a perfect structural balance. This process drastically improves weld strength and 100% eliminates the risk of oil leakage.
- High-Durability COB Copper Bushings: Equipped with top-tier domestic COB copper bushings. Although they require a higher material investment, they offer superior heat dissipation, a lower friction coefficient, and an unmatched lifespan compared to standard alternatives.
