Name: Festo 557206 Compact air cylinder ADNGF-5/8"-1/4"-P-A
Brand: Festo

Compact air cylinder ADNGF-5/8"-1/4"-P-A

The Festo 557206 is a double-acting industrial component featuring a 5/8" piston diameter, a 0.25 in stroke, and a profile barrel structural design compliant with ISO 21287. Equipped with elastic cushioning rings at both ends, a guide rod with yoke for torsion protection, and position sensing capabilities for proximity sensors, this unit operates within a pressure range of 1 bar to 10 bar. It delivers a theoretical retracting force of 20.2 lbf and an advancing force of 27.2 lbf at 6 bar while functioning across 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.
