Supplier's note

  1. Technical Breakthroughs:

    • The dual-sealed design reduces maintenance by 40% compared to open bearings.
    • P6 precision minimizes radial runout by ±0.006 mm, critical for precision machinery.
    • Chrome steel rollers provide 25% higher fatigue resistance than conventional steel.

  2. Optimal Version Selection:

    • Base Model (AS8): Ideal for standard industrial applications requiring moderate loads and basic corrosion resistance.
    • Advanced Model (TSS8): Suitable for high-speed machinery (e.g., automotive engines) needing oil/grease flexibility.
    • Pro Model (NSS8): Best for harsh environments (e.g., chemical plants) where extreme load and corrosion resistance are paramount. With its tripled corrosion resistance, it enables safe handling of corrosive fluids while maintaining high-speed efficiency.

*Note: Comparative values assume industry-standard benchmarks for similar bearing classes.
