Festo
557018
Compact cylinder ADN-1/2"- -
The Festo 557018 is a double-acting industrial component built on the ISO 21287 norm featuring a 1/2-inch piston diameter, a stroke length ranging from 0.039 inches to 11.8 inches, and elastic cushioning rings or pads at both ends. Designed with a piston, piston rod, and profile barrel, this unit operates with compressed air per ISO 8573-1:2010 [7:4:4] across an operating pressure range of 14.5 psi to 145 psi. It delivers a theoretical force of 11.5 lbf retracting and up to 15.3 lbf advancing at 6 bar, while accommodating an ambient temperature range of -4 °F to 248 °F.

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.
