Festo
161239
Flat cylinder DZF-18-40-A-P-A
The Festo 161239 is a double-acting industrial component featuring an 18 mm equivalent piston diameter, a 40 mm stroke, and an M8 piston rod thread with a single-end rod variant and oval piston providing an antitorsion guide up to 0.2 Nm max. torque and a +/- 1.2 degree maximum angle of rotation. Operating within a pressure range of 1 bar to 10 bar using compressed air per ISO 8573-1:2010 [7:4:4], this unit incorporates elastic cushioning rings at both ends, position sensing via proximity switch, and a corrosion resistance class of 2 for ambient temperatures from -20 °C to 80 °C. Delivering a theoretical retracting force of 123 N at 6 bar, it supports oil lubrication operation and achieves 0.1 J impact energy in the end positions with any mounting position.

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.
