Festo
548538
Round cylinder DSNU-1 1/4"- -PPV-A
The Festo part number 548538 is a double-acting industrial component featuring a 1 1/4" piston diameter, a 3/8-24 UNF-2A piston rod thread, and an adjustable pneumatic cushioning system at both ends based on the ISO 6431 norm. It operates within a pressure range of 1 bar to 10 bar utilizing compressed air as per ISO 8573-1:2010 [7:4:4], delivering a theoretical retracting force of 83 lbf at 6 bar across an adaptable stroke length spanning from 0.4 inches to 20 inches. This variant includes a single-ended piston rod with external threading, position sensing via proximity switch, and a corrosion resistance class of 2 for moderate stress environments within an ambient temperature range of -4 °F to 176 °F.
