Festo
162978
Flat cylinder DZF-2 1/2"- -A-P-A
The Festo 162978 is a double-acting industrial component featuring a 2 1/2" equivalent piston diameter, an adjustable stroke ranging from 0.04 in to 13 in, and a 5/8-18 UNF-2A piston rod thread. This unit utilizes an oval piston for torsion protection with a maximum rotation angle of +/- 0.4 degrees, elastic cushioning rings at both ends, and position sensing via proximity switch. Operating on compressed air within a 1 bar to 10 bar pressure range and -4 °F to 176 °F ambient temperature, it delivers a theoretical retracting force of 378 lbf 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.
