Supplier's note

  1. Technical Breakthroughs:

    • Material Hardness: The Pro Model’s 62 HRC rating exceeds industry standards, enabling resistance to pitting and deformation in high-stress environments.
    • Load Capacity: Advanced and Pro versions outperform base models by 20–40%, ideal for heavy machinery and industrial engines.
    • Compatibility: Direct-fit design eliminates adapter requirements, reducing downtime during engine rebuilds.

  2. Version Selection Guide:

    • Base Model: Suitable for standard diesel engine maintenance or light commercial use.
    • Advanced Model: Recommended for agricultural or construction equipment needing enhanced durability.
    • Pro Model: Engineers handling extreme loads (e.g., marine or mining applications) benefit from its 40% higher load capacity and corrosion-resistant alloy.

With the Pro Model’s aircraft-grade alloy, you can achieve triple the fatigue resistance of traditional steel, ensuring reliability in corrosive marine environments. Pair its 62 HRC hardness with high-RPM diesel engines to maximize power output while minimizing wear.
