Ball screws are high-precision linear motion components that convert rotational motion into linear motion. By placing ball bearings between the screw shaft and ball nut, they significantly reduce friction and achieve highly efficient power transmission. Widely used in positioning mechanisms for NC machine tools, CNC equipment, industrial robots, and automation systems, they are ideal for applications requiring high precision, high rigidity, and long service life. Compared to lead screws and trapezoidal screws, ball screws have minimal backlash and superior repeatability, making them frequently adopted in precision machining equipment and inspection devices.
