Linear Actuators are a mechanical device used to develop force and linear motion from a source of energy. The force is translated into a linear motion rather than a rotational motion as an electrical motor would have it. The Linear Actuators convert rotary motion into linear displacement by screws or gears to which the electric motor is attached. Linear Actuators are components of a motion system used to restrict an object to a single axis of motion. All Linear Actuators consists of a platform and a base, joined by some form of guide or linear bearing. The platform of the Linear Actuators is restricted to linear motion with respect to the base. The term Linear Actuators may or may not also include the mechanism by which the position of the platform is controlled relative to the base.
