Festo
539439
Compact cylinder ADNP-20-25-I-P-A-QS-4
This Festo industrial component, part number 539439, is a double-acting compact cylinder featuring a 20 mm piston diameter, a 25 mm stroke, and an ISO 21287 design structure with a female M6 piston rod thread. Operating on dried compressed air at working pressures from 0.6 to 10 bar, the unit provides flexible cushioning rings at both ends, position detection for proximity sensors, and theoretical forces of 188 N on the advance stroke and 141 N on the return stroke at 6 bar. It functions within an ambient temperature range of -10 to 60 °C and exhibits a CRC 2 corrosion resistance classification, a moving mass of 20 g at 0 mm stroke, and an additional weight of 17 g per 10 mm stroke.
