Festo
548478
Round cylinder DSNU-1 1/4"- -P
The Festo 548478 is a double-acting industrial component featuring a 1 1/4" piston diameter, a 3/8-24 UNF-2A male piston-rod end, 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 and a single-ended piston rod, this unit operates on compressed air complying with ISO 8573-1:2010 [7:4:4] within a pressure range of 1 to 10 bar. It delivers a theoretical retracting force of 83 lbf at 0.6 MPa (87 psi) and functions within an ambient temperature range of -4 to 176 °F with moderate corrosion stress resistance (CRC 2).
