An electric cylinder is a modular product that integrates a servo motor and a lead screw into a unified design. It converts the rotational motion of the servo motor into linear motion, while also transforming the servo motor's key advantages—precise rotational speed control, precise rotation count control, and precise torque control—into precise speed control, precise position control, and precise thrust control. It is an innovative and revolutionary product that enables a series of high-precision linear motion applications.
