Linear actuators are a vital component used in many different kinds of machines. Smaller actuators are also found in simple disk drives as well as dampers and valves. The larger-sized actuators are used in different kinds of industrial machines. They are generally used to produce mechanical activity within a machine, and usually have a particular mechanism fitted inside that converts rotary motion into linear motion.
