Festo
557045
Compact cylinder ADN-5/8"-2"-I-P-A
The Festo 557045 is a double-acting industrial component featuring a 5/8" piston diameter, a 2 in stroke, and a profile barrel structural design with a piston rod at one end having an 8-36 UNF-2B internal thread. Built to ISO 21287 standards, this unit operates on compressed air within a pressure range of 14.5 psi to 145 psi and includes elastic cushioning rings at both ends to absorb 0.111 ft-lbf of impact energy. It delivers a theoretical force of 27.2 lbf advancing and 20.2 lbf retracting at 6 bar, supports position sensing via proximity switch, and offers moderate corrosion resistance with a CRC rating of 2.

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.
