Festo
548519
Round cylinder DSNU-2 1/2"- -P-A-S2
The Festo 548519 is a double-acting industrial component featuring a 2 1/2" piston diameter, a through piston rod with a 5/8-18 UNF-2A external thread, and an adjustable stroke ranging from 0.4 in to 20 in based on ISO 6431. Built with elastic cushioning rings at both ends, this unit operates within a pressure range of 1 bar to 10 bar using compressed air conforming to ISO 8573-1:2010 [7:4:4] and delivers a theoretical force of 374 lbf advancing and 336 lbf retracting at 6 bar. It incorporates position sensing via proximity switch, moderate corrosion resistance class (CRC 2) construction, and an ambient temperature operating range of -4 °F to 176 °F in 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.
