U-Series Linear Actuators

Ultra Motion’s U-Series of pressure-compensated oil-filled linear actuators has been designed to deliver highly reliable performance for surface and subsea platforms such as UUVs (unmanned underwater vehicles) and USVs (uncrewed surface vessels), and is able to withstand depths of over 6000 metres. The product range offers a wide variety of options to suit specific requirements, including stepper motors or brushless DC motors, in-line planetary gearheads, self-locking Acme leadscrews or high-efficiency ballscrews, and stroke lengths from 1 to 16 inches.

All U-series actuators feature an internal linear potentiometer for absolute position feedback, and require external motor control electronics. For subsea linear actuators with built-in control electronics, see Ultra Motion's AU Servo Cylinder series.

U-Series actuators are equipped with SubConn Wet-Mate connectors as standard, and can be provided with custom cable lengths and output formats upon request.
