Festo
548481
Round cylinder DSNU-2 1/2"- -P
The Festo 548481 is a double-acting industrial component featuring a 2 1/2" piston diameter, a 5/8-18 UNF-2A male piston rod thread, and a stroke length ranging from 0.04 to 20 inches based on the ISO 6431 standard. Designed with flexible cushioning rings at both ends, this unit operates within a pressure range of 1 to 10 bar (0.1 to 1 MPa) using compressed air conforming to ISO 8573-1:2010 [7:4:4] and provides a theoretical retracting force of 336.38 lbf at 0.6 MPa. It functions within an ambient temperature span of -4 to 176 °F, achieves an impact energy of 0.9588 ft-lbf in its end positions, and features a CRC 2 moderate corrosion resistance classification with any assembly position.
