Festo
11311
Standard cylinder DSN-5/16"-1/2"-P
The Festo 11311 is a double-acting industrial component built to ISO 6432 standards featuring a 12.7 mm stroke and a 5/16" piston diameter with a male thread piston-rod end. It operates within a 1 to 10 bar pressure range using dried compressed air, delivering a theoretical force of 22.6 N on the return stroke and 30.2 N on the advance stroke at 6 bar. Constructed with a wrought aluminium alloy cover, high alloy non-corrosive steel for the cylinder barrel and piston rod, and NBR and TPE-U(PU) seals, the unit includes elastic cushioning rings on both sides and an M12x1,25 pneumatic connection for ambient temperatures from -20 to 80 °C with a CRC 2 corrosion resistance classification.

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.
