Festo
559251
Standard cylinder DSNU-25-40-PPS
The Festo 559251 is a double-acting industrial component featuring a 25 mm piston diameter, a 40 mm stroke, and an M10x1,25 male piston-rod thread conforming to ISO 6432 and CETOP RP 52 P standards. Operating on compressed air within a 1 to 10 bar pressure range and -20 to 80 °C ambient temperatures, it utilizes self-adjusting pneumatic end-position cushioning (PPS) with a 17 mm cushioning length and 0.3 J end-position impact energy. This single-ended piston rod design delivers theoretical forces of 294.5 N on the advance stroke and 247.4 N on the return stroke at 6 bar.
