Festo
559281
ISO cylinder DSNU-20-320-PPS-A
The Festo 559281 is a double-acting industrial component featuring a 20 mm piston diameter, a 320 mm stroke, and an M8 external thread piston rod at one end conforming to ISO 6432 and CETOP RP 52 P standards. Operating within a pressure range of 1 bar to 10 bar using compressed air per ISO 8573-1:2010 [7:4:4], this unit utilizes self-adjusting pneumatic end-position cushioning across a 15 mm cushioning length with 0.2 J impact energy. Designed with a structural layout of piston, piston rod, and cylinder barrel for any mounting position, the assembly accommodates position sensing via proximity switch, operates in ambient temperatures from -20 °C to 80 °C, and achieves ISO 14644-1 Class 6 cleanroom suitability with a CRC 2 moderate corrosion resistance rating.
