Festo
548540
Round cylinder DSNU-2"- -PPV-A
The Festo 548540 is a double-acting industrial component featuring a 2-inch piston diameter, a 5/8-18 UNF-2A piston rod thread, and an adjustable pneumatic cushioning system at both ends based on the ISO 6431 norm. It operates within a pressure range of 1 bar to 10 bar and an ambient temperature span of -4 °F to 176 °F, accommodating strokes from 0.4 inches to 20 inches with a piston rod at one end. Position sensing is achieved via proximity switch, supporting a theoretical retracting force of 198 lbf at 6 bar and an impact energy of 0.738 ft-lbf 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.
