M thrust motorized screw actuators. Offer backlash free motion of the shafts with load capacity. 70 N. Travel range 25 mm. With resolution of 0.1 micron. Moving shaft actuators are direct drive linear. Servo motors or motorized screws actuators with moving center shafts these actuators have short working stroke (5 to 30 mm.) and high resolution to 0.1 micron and allow user precision and force control. It could be paired with electronic speed control for motor speed. Or used with stepper motors for precision linear movement.
