Advanced Friction Material Technology
The 402xxx series for Adams graders requires superior heat dissipation. Our aftermarket components utilize Sintered Bronze (MCFK SI), which offers unique advantages:
- Thermal Stability: Maintains a consistent friction coefficient (μ ≈ 0.35) up to 350°C.
- Wear Resistance: High-density copper matrix extends service life in high-torque environments.
- Shear Strength: Reinforced teeth structure to prevent mechanical failure during intense grading.
Our Quality Assurance Protocols
To ensure 100% fitment and performance, every batch undergoes strict QC:
- CNC Machining: Thickness tolerances are maintained within ±0.05mm.
- Hardness Verification: Rockwell hardness testing (HRB) for structural integrity.
- Surface Finish: Precision grinding for optimal mating plate engagement.
