Festo
171421
Round cylinder DSAS-16- -P-A
The Festo 171421 is a double-acting industrial component featuring a 16 mm piston diameter and an adjustable stroke length from 1 to 250 mm. Operating within a pressure range of 1 to 10 bar, this unit delivers a theoretical retraction force of 103.7 N and an advance force of 120.6 N at 0.6 MPa using compressed air conforming to ISO8573-1:2010 [7:4:4]. Constructed with a non-corrosive high alloy steel housing, wrought aluminum alloy cover, NBR and TPE-U(PU) seals, and flexible cushioning rings at both ends, it operates in ambient temperatures between -20 and 80 °C under moderate corrosion stress (CRC 2).

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.
