What is a linear actuator and how is it made?

Linear actuators offer a potentially simple and quick solution for an X-Y or X-Y-Z stage. Belt driven actuators are very useful for long stroke applications, where strokes in excess of 10m are possible.

Positioning linear actuator construction is often an aluminium extrusion, to which linear guide rails are fitted, with drive coming from either a belt or ball screw. A variety of motors are fitted according to the application.
