Name: Festo 548539 Round cylinder DSNU-1 5/8"- -PPV-A
Brand: Festo

Round cylinder DSNU-1 5/8"- -PPV-A

The Festo part number 548539 is a double-acting industrial component featuring a 1 5/8" piston diameter, a 1/2-20 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 (0.1 MPa to 1 MPa) across ambient temperatures from -4 °F to 176 °F, utilizing compressed air as per ISO 8573-1:2010 [7:4:4] with oil lubrication support. This variant incorporates position sensing via a proximity switch, a 0.4 in to 20 in stroke, and yields a theoretical retracting force of 127 lbf at 6 bar while maintaining a corrosion resistance class of 2 and VDMA24364-B1/B2-L LABS conformity.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
