Name: Festo 557088 Compact cylinder ADN-1 1/4"-2 1/2"-A-P-A
Brand: Festo

Compact cylinder ADN-1 1/4"-2 1/2"-A-P-A

The Festo 557088 is a double-acting industrial component featuring a 1 1/4" piston diameter, a 2.5 in stroke, and a 3/8-24 UNF-2A external piston rod thread based on the ISO 21287 norm. This compact unit operates on compressed air within a pressure range of 14.5 psi to 145 psi, utilizing elastic cushioning rings at both ends and integrated position sensing via proximity switch. It delivers a theoretical force of 109 lbf advancing and 93.3 lbf retracting at 6 bar, with a moderate corrosion resistance class (CRC 2) and an ambient temperature range of -4 °F to 176 °F.

Why 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.
