Festo
548551
Round cylinder DSNU-2 1/2"- -P-S2
The Festo 548551 is a double-acting industrial component featuring a 2 1/2" piston diameter, 5/8-18 UNF-2A male piston rod thread, and through piston rod design based on the ISO 6431 standard. It operates within a pressure range of 1 to 10 bar (0.1 to 1 MPa), utilizing compressed air in accordance with ISO 8573-1:2010 [7:4:4] with flexible cushioning rings at both ends and an adjustable stroke from 0.04 to 20 inches. Rated for ambient temperatures between -4 and 176 °F, this unit delivers a theoretical retracting force of 336.38 lbf at 0.6 MPa (87 psi) and exhibits a moderate corrosion resistance classification of CRC 2.
