Festo
548517
Round cylinder DSNU-1 5/8"- -P-A-S2
The Festo part number 548517 is a double-acting industrial component with a 1 5/8" piston diameter, an adjustable stroke from 0.4 in to 20 in, and a 1/2-20 UNF-2A external piston rod thread based on the ISO 6431 norm. Operating at pressures between 1 bar and 10 bar using compressed air per ISO 8573-1:2010 [7:4:4], it features elastic cushioning rings at both ends, position sensing via proximity switch, and through piston rod variants with a moderate corrosion resistance class of CRC 2. This unit delivers a theoretical force of 151 lbf advancing and 127 lbf retracting at 6 bar within an ambient temperature range of -4 °F to 176 °F.

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.
