Festo
557020
Compact cylinder ADN-1/2"-1/2"-A-P-A
The Festo 557020 is a double-acting industrial component based on the ISO 21287 norm, featuring a 1/2-inch piston diameter and a 0.5-inch stroke. This unit utilizes a profile barrel design with a 10-32 UNF-2A external piston rod thread at one end, elastic cushioning rings at both ends, and position sensing via proximity switch. It operates within a pressure range of 14.5 psi to 145 psi on compressed air conforming to ISO 8573-1:2010 [7:4:4], delivering a theoretical advancing force of 15.3 lbf and retracting force of 11.5 lbf at 6 bar.

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.
