Supplier's note

1. Technical Breakthroughs:

   • GCr15 Steel: 20% higher hardness than standard chromium steel, extending lifespan in abrasive environments.
   • ISO C3 Precision: Achieves ±5 arc-seconds accuracy, 50% tighter than industry average.
   • Pre-loaded Design: Eliminates backlash entirely, unlike traditional screws with 2–5 μm tolerances.

2. Version Selection Guide:

   • Base Model: Ideal for standard automation (e.g., 3D printers) where cost-efficiency is critical.
   • Advanced Model: Suited for industrial robotics needing 20% higher load capacity than baseline applications.
   • Pro Model: Best for heavy-duty automation (e.g., semiconductor equipment) requiring 4000 RPM speeds and triple the fatigue resistance of industry benchmarks.

*Pro Model exceeds ISO 3408 fatigue life standards by 30%.
