Abstract
An actuator is disclosed that utilizes a fixed screw attached at one end to an actuator housing. A rotatable tube concentric with the fixed screw rotationally drives a nut having threads engaging the threaded shaft, such that the nut moves axially relative to the tube, upon rotation of the tube. The actuator is axially coupled to the nut by thrust bearings such that the actuator rod does not rotate with the driven member.
