Festo
539402
Compact cylinder ADNP-25-20-A-P-A-QS-4
The Festo 539402 is a double-acting industrial component featuring a 25 mm piston diameter, a 20 mm stroke, and an M8 piston rod thread designed with a male end and a single-ended piston rod based on ISO 21287. Operating on dried compressed air at a working pressure of 0.6 to 10 bar, this unit delivers theoretical forces of 295 N on the advance stroke and 247 N on the return stroke at 6 bar. It incorporates flexible cushioning rings at both ends, position detection capabilities for proximity sensors, and a CRC 2 corrosion resistance classification for operation within an ambient temperature range of -10 to 60 °C.
