Festo
559261
Standard cylinder DSNU-25-400-PPS
The Festo part number 559261 is a double-acting industrial component featuring a 25 mm piston diameter, a 400 mm stroke, and a single-ended piston rod with an M10x1,25 male thread. Conforming to ISO 6432 and CETOP RP 52 P standards, it operates on compressed air within a 1 to 10 bar pressure range and a -20 to 80 °C ambient temperature span. Self-adjusting pneumatic end-position cushioning (PPS) manages a 0.3 J impact energy across its 17 mm cushioning length while delivering theoretical forces of 294.5 N on the advance stroke and 247.4 N on the return stroke at 6 bar.
