Festo
571938
Compact cylinder ADNP-25-20-A-P-A
The Festo part number 571938 is a double-acting industrial component featuring a 25 mm piston diameter, a 20 mm stroke, and an M8 male piston rod thread based on the ISO 21287 standard. Operating on compressed air in accordance with ISO 8573-1:2010 [7:4:4] within a 0.6 to 10 bar working pressure range, this unit incorporates flexible cushioning rings at both ends and provisions for proximity sensor position detection. It delivers a theoretical force of 295 N on the advance stroke and 247 N on the return stroke at 6 bar, with a moderate corrosion resistance classification of CRC 2 and an ambient temperature range of -10 to 60 °C.
