Ball Screw Motor (Series 20, 28, 35, 42, 57)

Product Overview

Ball screws are the most commonly used transmission components in machine tools and precision machinery. Their main function is to convert rotary motion into linear motion or convert torque into axial repetitive force, featuring high precision, good reversibility, and high efficiency. Ball screws have low friction resistance and are widely used in various industrial equipment and precision instruments.
