Abstract
A ball screw and nut linear actuator has a motor and a ball nut and screw assembly in side by side disposition. Gearing connects with the motor shaft to drive the screw and a housing for the gearing and ball nut and screw assembly includes an elongate housing tube within which the screw assembly is housed. The nut incorporates an extension sleeve assembly for extending movement out of the housing tube which anchors the screw against axial movement while jounaling it for rotation. A pin and axial track connection between the extension sleeve assembly and the housing tube guides the extension sleeve assembly in axial movement and prevents relative rotation of the housing tube and sleeve assembly.
