Festo
33509
Standard cylinder ESNU-3/8"- -P-A
The Festo 33509 is a single-acting industrial component operating via a pushing action with a 3/8" piston diameter and an adjustable stroke of 10 to 50 mm based on the ISO 6432 standard. Designed for an operating pressure of 1.2 to 10 bar using dried compressed air, it delivers a theoretical advance force of 41.6 N at 6 bar and features flexible cushioning rings or plates at both ends. Constructed with a wrought aluminium alloy cover, a non-corrosive high alloy steel housing and piston rod, and NBR and TPE-U(PU) seals, this unit operates in ambient temperatures from -20 to 80 °C with a CRC corrosion resistance of 2 and an M12x1,25 pneumatic connection.
