Festo
557076
Compact cylinder ADN-1"-1 1/4"-I-P-A
This Festo industrial component, part number 557076, is a double-acting pneumatic actuator featuring a 1-inch piston diameter, a 1.25-inch stroke, and an ISO 21287 profile barrel design with internal 10-32 UNF-2B piston rod threads. Operating within a pressure range of 14.5 psi to 145 psi (1 bar to 10 bar), the unit utilizes compressed air per ISO 8573-1:2010 [7:4:4] and delivers theoretical forces of 66.3 lbf advancing and 55.5 lbf retracting at 6 bar. It incorporates elastic cushioning rings at both ends, position sensing via proximity switch, and offers moderate corrosion resistance (CRC 2) across an ambient temperature range of -4 °F to 176 °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.
