Festo
156721
Compact air cylinder ADVULQ-40-80-P-A
The Festo 156721 is a double-acting industrial component featuring a 40 mm piston diameter, an 80 mm stroke, and a square piston rod that provides anti-torsion guidance. Operating within a pressure range of 1 to 10 bar (14.5 to 145 psi), this unit utilizes compressed air per ISO 8573-1:2010 [7:4:4] and incorporates elastic cushioning rings at both ends to absorb a 0.52 J impact energy in the end positions. It delivers a theoretical force of 754 N advancing and 686 N retracting at 6 bar, supports position sensing via proximity sensors, and maintains a moderate corrosion resistance class rating of CRC 2 across an ambient temperature range of -20 °C to 80 °C.

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.
