Festo
546377
Compact cylinder ADVU-5/8"-1 1/4"-P-A
The Festo 546377 is a double-acting industrial component featuring a 5/8" piston diameter, a 1.25" stroke, and a female thread piston-rod end with a UNF10-32 pneumatic connection. Operating on filtered compressed air at a working pressure range of 17.4 to 145 psi, it utilizes flexible cushioning rings/plates at both ends (P cushioning) and TPE-U(PU) and NBR dynamic seals housed in a wrought aluminum alloy cover. The unit delivers a theoretical return force of 20 lbf and an advance force of 27 lbf at 6 bar, with a basic weight of 3.139 oz for a 0 mm stroke, an ambient temperature range of -4 to 176 °F, and a CRC corrosion resistance classification of 2.
