Supplier's note

  1. Technical Breakthroughs:

    • Material Innovation: 40Cr steel provides 20% higher tensile strength than standard pins.
    • Corrosion Resistance: The Pro model’s military-grade coating outperforms industry benchmarks by 50%.
    • Load Capacity: Advanced and Pro models handle 20–40% heavier loads than base versions.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard excavators (e.g., small to medium Caterpillar machines) requiring cost-effective durability.
    • Advanced Model: Best for high-cycle applications like Komatsu hydraulic systems, where +20% load capacity prevents premature wear.
    • Pro Model: Designed for extreme environments (e.g., Wirtgen asphalt recyclers) needing corrosion resistance and 7000 N load capacity.

Example: With the Pro model’s military-grade coating, you can ensure zero corrosion in saltwater ports. Its 7000 N capacity paired with 40Cr+ nitriding allows seamless operation in abrasive mining conditions.
