Festo
557278
Compact air cylinder ADNGF-3"-3"-P-A
The Festo 557278 is a double-acting industrial component featuring a 3-inch piston diameter and a 3-inch stroke based on the ISO 21287 norm. This unit utilizes a profile barrel structural design with a piston rod, guide rod with yoke for torsion protection, and elastic cushioning pads at both ends accommodating an impact energy of 1.33 ft-lbf. It operates within a pressure range of 1 bar to 10 bar using compressed air per ISO 8573-1:2010 [7:4:4], delivering theoretical forces of 678 lbf advancing and 636 lbf retracting 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.
