Festo
177949
Profile cylinder DNC-2 1/2"-4"-P-A
This Festo industrial component, part number 177949, is a double-acting pneumatic cylinder featuring a 2 1/2" piston diameter, a 4" stroke, and a 5/8-18 UNF-2A male piston rod thread based on the ISO 15552 standard. Operating with compressed air in accordance with ISO 8573-1:2010 [7:4:4] across a working pressure range of 0.6 to 12 bar, the unit incorporates flexible cushioning rings at both ends and delivers a theoretical retracting force of 1,682 N at 0.6 MPa. Designed with a profile barrel structure and position detection for proximity sensors, it functions within an ambient temperature range of -20 to 80 °C and exhibits a CRC 2 moderate corrosion resistance classification.
