Festo
161238
Flat cylinder DZF-18-25-A-P-A
The Festo 161238 is a double-acting industrial component featuring an 18 mm equivalent piston diameter, a 25 mm stroke, and an M8 piston rod thread at one end. Designed with an oval piston providing a maximum rotation protection torque of 0.2 Nm and an angle tolerance of +/- 1.2 degrees, this unit operates between 1 bar and 10 bar using compressed air in ambient temperatures from -20 °C to 80 °C. Position sensing is achieved via a proximity switch, while elastic cushioning rings at both ends absorb a 0.1 J impact energy in the end positions.

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.
