Festo
557040
Compact cylinder ADN-5/8"-1/2"-I-P-A
The Festo part number 557040 is a double-acting industrial component featuring a 5/8" piston diameter and a 0.5 in stroke based on the ISO 21287 norm. This profile barrel unit operates within a pressure range of 14.5 psi to 145 psi using compressed air as per ISO 8573-1:2010 [7:4:4], delivering a theoretical retracting force of 20.2 lbf and an advancing force of 27.2 lbf at 6 bar. It incorporates elastic cushioning rings at both ends, internal 8-36 UNF-2B piston rod threads at one end, and position sensing via proximity switch.

Request a QuoteWhy 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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
