Festo
34939
Standard cylinder DNGZK-40- -PPV-A-S3
The Festo 34939 is a double-acting industrial component featuring a 40 mm piston diameter, an M12x1,25 piston rod thread, and an adjustable pneumatic cushioning (PPV) system at both ends based on the ISO 15552 standard. Operating within a pressure range of 0.6 to 12 bar and an ambient temperature of -20 to 80 °C, this unit delivers a theoretical force of 754 N on the advance stroke and 633 N on the return stroke at 6 bar using compressed air meeting ISO 8573-1:2010 [7:4:4]. It includes position detection for proximity sensors, a stroke length ranging from 1 to 2,000 mm, and variants featuring a stainless steel corrosion- and acid-resistant piston rod.

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
