8mm round nut ball screw for laser cutting  

Product Description 8mm Diameter Miniature Ball Screw with factory price for CNC machine Ball screws are ideal products for converting rotary motion into linear motion, or converting linear motion into rotary motion. Ball screw is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert rotary motion into linear motion, or convert torque into axial repetitive force, with high precision, reversibility and high Efficiency characteristics. Due to its small frictional resistance, ball screws are widely used in various industrial equipment and precision instruments. The ball screw consists of a screw, a nut, a steel ball, a pre-press, a reverser, and a dust filter. Its function is to convert rotary motion into linear motion, which is a further extension and development of Acme screw. The important significance of this development is to change the bea…
