Supplier's note

  1. Technical Breakthroughs:

    • GCr15 Steel: 20% higher tensile strength than standard steel, enabling robust performance in corrosive environments.
    • Double Nut Design: Reduces backlash by 50%, ensuring precision in high-cycle applications.
    • Custom Thread Pitch: Balances speed and accuracy, with coarse pitch (+20% faster than fine pitch) for rapid movement.
  2. Version Selection Guide:

    • Base Model: Ideal for light-duty CNC routers or prototyping (e.g., small workshop setups).
    • Advanced Model: Best for industrial automation with frequent cycles (e.g., robotic arms needing backlash reduction).
    • Pro Model: Designed for heavy machinery (e.g., 5-axis CNC mills) requiring triple the industry-standard load capacity.

With the Pro’s 6500 N load capacity, you can handle heavy-duty automation tasks without compromising speed. Pair its GCr15 steel with a double nut to achieve zero-play motion in corrosive environments. The Advanced model’s 50% backlash reduction ensures reliability in high-precision robotics.
