Linear thrusters use double-acting pneumatic, hydraulic, or electrohydraulic cylinders mated to plates and shafts to provide cyclical linear motion.

Hydraulic linear actuators use a cylinder and hydraulic fluid for motive force

Piezoelectric actuators are devices that produce a small displacement with a high force capability when voltage is applied.

Electric linear actuators have an output rod that provides linear motion via a motor driven ball screw, lead screw, or ACME screw assembly.

Electrohydraulic valve actuators and hydraulic valve actuators convert fluid pressure supply pressure into motion

Voice coil actuators and motors generate force when subjected to an electrical current or magnetic field.

Electric rotary actuators drive components rotationally via electromagnetic power.
