Festo
171856
Round cylinder DSAS-25- -P-A
The Festo 171856 is a double-acting industrial component featuring a 25 mm piston diameter and an adjustable stroke length from 1 to 500 mm, operating within a pressure range of 1 to 10 bar using compressed air according to ISO8573-1:2010 [7:4:4]. Constructed with a non-corrosive high alloy steel housing, wrought aluminum alloy cover, and NBR and TPE-U(PU) seals, this unit provides flexible cushioning rings at both ends and achieves theoretical forces of 294.5 N advancing and 247.4 N retracting at 0.6 MPa. It functions within an ambient temperature range of -20 to 80 °C, exhibits a CRC 2 moderate corrosion resistance classification, and supports lubricated operation.
