Product Description
Heavy-Duty ZAX200 / ZX200 Track Roller for Excavator Undercarriage Replacement
Are you looking to eliminate frequent equipment downtime and lower your machinery's maintenance costs? Our premium ZAX200 / ZX200 Track Roller (also known as Bottom Roller or Lower Roller) is meticulously engineered to endure extreme loads and highly abrasive environments. Perfect for heavy-duty mining and rugged construction applications, this roller ensures your crawler machinery operates at peak efficiency.
Advanced Manufacturing & Technological Advantages
- Premium Forged 40Mn2 Steel: We utilize genuine, high-density original 40Mn2 steel to guarantee exceptional structural density. Through precise induction heat treatment, the surface hardness reaches HRC 50-55, providing outstanding wear resistance and preventing cracking under severe impacts.
- Japanese Friction Welding Technology: Manufactured using advanced friction welding technology imported from Japan to ensure a perfect structural balance. This process drastically increases welding strength and 100% eliminates the risk of oil leakage or shell separation.
- High-Durability COB Copper Bushings: Equipped with top-tier domestic COB copper bushings. Although they require a higher material investment, they provide superior heat dissipation, a lower friction coefficient, and an unmatched operational life compared to standard alternatives.
