💡 Why are large diameter ball screws used in heavy duty CNC motion systems?
Large diameter ball screws are designed to handle higher loads while keeping motion smooth and accurate.

• Supports high axial loads with strong stiffness and stability

• Improves positioning accuracy in large CNC and industrial machines

• Reduces friction and heat compared to traditional lead screws

• Allows high speed travel and precise micro feeding under load

This ball screw is a handy choice when you need strong load capacity, smooth transmission, and dependable accuracy in professional CNC and industrial motion applications.
