Abstract: A linear hydraulic motor is disclosed in combination with an actuator arm wherein the drive is so mounted with respect to the journaling of the arm that manufacturing tolerances may be considerably relaxed while still maintaining extremely accurate and rigid arm positioning. This is accomplished by maintaining full pressure on all arm actuators when the arm is not actually being moved and at the same time mounting said hydraulic motor in a rotational orientation with respect to the bearings supporting said arm. A special aligning rack and piston system is utilized to assure fine positioning of the arm and the system is particularly well adapted for use as a positioning actuator for use with robotized assembly lines and the like.
