A captive leadscrew-type linear actuator assembly has a motor whose rotor has a rearward extending hollow bore shaft. An external nut assembly fixed to the bore shaft to rotate with rotor engages a lead screw. An anti-rotation radial support plate attaches to a front of the motor with a non-circular hole that prevents rotation of a rod or piston attached to the lead screw. Accordingly, torque applied by the rotor through the nut to the lead screw is converted into linear motion wherein the rod or piston passes through the hole. Replaceable external components lead to greater design flexibility together with improved motion accuracy and durability.
