Product overviewDouble-stack stepper ball screw actuator for precise linear positioning in industrial motion control. 28-Series Size 11 (46 mm body) with 1.8° step angle; double-stack configuration increases axial force and stroke capacity compared with single-stack variants.
WiringBipolar. Compatible with common bipolar constant-current drivers and microstepping controllers; suitable for open- and closed-loop motion systems.
