Festo
177939
Profile cylinder DNC-2 1/2"-8"-P
The Festo 177939 industrial component is a double-acting piston actuator featuring a 2 1/2" piston diameter, an 8" stroke, and a 5/8-18 UNF-2A male piston rod thread based on the ISO 15552 standard. Built with a profile barrel and flexible cushioning rings at both ends, it operates on compressed air complying with ISO 8573-1:2010 [7:4:4] within a pressure range of 0.06 to 1.2 MPa and an ambient temperature span of -20 to 80 °C. This single-ended rod variant provides a theoretical retracting force of 1,682 N at 0.6 MPa and features a CRC 2 moderate corrosion resistance classification with any assembly position.
