Festo
14140
Standard cylinder DNU-40-250-PPV-A
The Festo 14140 is a double-acting industrial component featuring a 40 mm piston diameter, a 250 mm stroke, and a male M12x1,25 piston rod thread conforming to ISO 6431. Operating within a pressure range of 0.6 to 12 bar and an ambient temperature span of -20 to 80 °C, this unit utilizes adjustable pneumatic cushioning at both ends with a 21 mm cushioning length. It accommodates dried compressed air in either lubricated or unlubricated formats, achieves position detection via proximity sensors, and delivers theoretical forces of 715 N on the advance stroke and 586 N on the return stroke at 6 bar.

Request a QuoteWhy no listed price?
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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
