Supplier's note

  1. Top Technical Breakthroughs:

    • High-Carbon Steel Pro Model: 30% stronger than cast iron, enabling use in heavy-duty mining generators.
    • Serrated Perimeter Design: Reduces clutch wear by 25% compared to flat-edge alternatives.
    • Balanced Weight Distribution: Minimizes vibration by 15%, extending engine lifespan.

  2. Version Selection Guidance:

    • Base Model: Ideal for basic agricultural or residential generators requiring cost-effective solutions.
    • Advanced Model: Suitable for commercial applications (e.g., construction equipment) needing moderate durability and wider engine compatibility.
    • Pro Model: Designed for industrial users (e.g., mining, marine) requiring extreme load handling and longevity. With its tripled corrosion resistance, it ensures safe operation in corrosive environments.

With the Pro Model’s high-carbon steel, you can handle 40% heavier loads than traditional cast iron flywheels. Pair this with its expanded year range, and you gain a universal solution for legacy and modern diesel systems.
