Chain actuators work much like rack and pinion actuators. A chain engages with pinions which have been installed on a drive shaft in a exterior casing. As the pinions spin, the links of the chain are rotated through the casing at a 90-degree angle. This directs the chain right into a rigid, straight 
form, which is highly resistant to stress and compression. For a power windows opener, the chain provides been mounted on a window. So as the chain is usually directed right into a straight form, the home window is pushed open. And as it retracts into the casing, the windowpane closes.
These are usually suited to side hung home windows or doors, because they provide a 90-degree opening. Also, they are called folding arm actuators and will be designed to open up inwards, outwards or both methods.
