Supplier's note

  1. Technical Breakthroughs:

    • Cross Roller Structure: Enables 20% higher load capacity vs. traditional slewing bearings.
    • GCr15 Steel: Offers 30% better corrosion resistance than standard carbon steel.
    • Precision Machining: Achieves rotational smoothness with ±0.01mm runout tolerance.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard industrial applications (e.g., small cranes, agricultural equipment).
    • Advanced Model: Recommended for heavy-duty machinery (e.g., construction excavators) requiring faster rotational speeds.
    • Pro Model: Designed for corrosive environments (e.g., offshore platforms) with extreme load demands. Its triple-standard corrosion resistance, paired with GCr15’s hardness, ensures safe operation in harsh chemical exposure scenarios.

*Pro Model’s load capacity exceeds industry benchmarks by 25%.
