Festo DNG-40-140-PPV-A Double Acting Pneumatic Cylinder

Festo DNG-40-140-PPV-A is a double acting pneumatic cylinder from Festo that provides reliable linear actuation for automation tasks. The unit features a 40 mm bore and a 140 mm stroke, where the bore size determines the piston area and potential force generation, and the stroke length defines how far the piston can travel in a single actuation cycle. In a double acting configuration, pressurized air drives both extension and retraction, enabling bidirectional motion without a separate return spring and allowing compact actuation hardware in many setups. The DNG-40-140-PPV-A designation identifies a specific model within Festo’s DNG family, signaling its place in the line of compact, standard pneumatic cylinders designed for integration into a wide range of industrial pneumatic circuits. Engineers use bore and stroke together to gauge whether the cylinder can achieve the required force under load and reach the target position within the available space, and to plan the corresponding valve actuation and cycle timing.
