- Exceptional Structural Integrity: By using 40Mn2 original forged steel instead of cast steel, our rollers eliminate internal porosity and offer superior structural density to withstand extreme impact load.
- Advanced Japanese Friction Welding: We implement imported Japanese friction welding machinery. This ensuring precise alignment, flawless joint balance, and prevents oil leakage or body separation under heavy stress.
- Extended Component Durability: Though slightly higher in material cost, our domestic COB copper bushings provide unmatched anti-friction capability and heavy-load durability compared to standard alternatives.
- Verified Track Record: Backed by years of contract manufacturing experience for world-renowned brands like ITR, our production quality management seamlessly satisfies the strict demands of international wholesalers and fleet managers.
