Festo
539396
Compact cylinder ADNP-20-40-A-P-A-QS-4
This Festo industrial component operates as a double-acting pneumatic cylinder based on the ISO 21287 standard featuring a 20 mm piston diameter, a 40 mm stroke, and an M8 male piston rod thread. Designed with flexible cushioning rings at both ends, a single-ended piston rod, and integrated position detection for proximity sensors, it functions within a working pressure range of 0.6 to 10 bar using dried compressed air. The unit delivers a theoretical return force of 141 N and advance force of 188 N at 6 bar while withstanding ambient temperatures from -10 to 60 °C with a CRC 2 corrosion resistance classification.
