The magnetic rodless cylinder is a modular product that integrates a servo motor and a lead screw. The magnetic type rodless cylinder converts the servo motor's rotational motion into linear motion, achieving a revolutionary new product in the high-precision linear motion series. The magnetically coupled cylinder internal structure includes planetary roller screws, roller screws, trapezoidal screws, and an anti-reverse device. The magnetically coupled pneumatic cylinder drive motor types include stepper motors, servo motors, DC motors, and AC motors. The magnetically coupled rodless air cylinder is widely used in the papermaking, chemical, automotive, electronics, mechanical automation, and welding industries.
