Festo
177961
Profile cylinder DNC-2 1/2"-3"-PPV
The Festo 177961 is a double-acting industrial component featuring a 2 1/2" piston diameter, a 3" stroke, and a 5/8-18 UNF-2A male piston-rod thread based on the ISO 15552 standard. Operating at a pressure range of 0.06 to 1.2 MPa with compressed air conforming to ISO 8573-1:2010 [7:4:4], this profile-barrel cylinder incorporates adjustable pneumatic cushioning at both ends with a 22 mm cushioning length. It functions in ambient temperatures from -20 to 80 °C, achieves a CRC 2 moderate corrosion resistance classification, and permits lubricated operation.
