Are you looking to reduce your heavy machinery's downtime and lower chassis maintenance costs? Our high-performance PC300 Track Roller (also commonly referred to as Bottom Roller or Lower Roller) is engineered to withstand extreme loads and harsh working environments. Perfect for heavy-duty mining and rugged construction sectors, this roller ensures your crawler equipment keeps moving with maximum efficiency.
Advanced Technical Advantages
- Premium Forged 40Mn2 Steel: Manufactured using genuine, high-density 40Mn2 steel for supreme structural integrity. Through precise induction heat treatment, the surface hardness reaches HRC 50-55, offering exceptional wear resistance and preventing cracking under severe impacts.
- Japanese Friction Welding Tech: We utilize advanced friction welding technology imported from Japan to achieve a flawless balance. This method drastically improves the weld 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 higher material investment, they provide superior heat dissipation, a lower friction coefficient, and unmatched wear life compared to standard alternatives.
