Festo
11143
Standard cylinder ESN-5/16"-1/2"-P
The Festo 11143 is a single-acting industrial component operating via a pushing action with a 5/16" piston diameter and a 0.5" stroke based on the ISO 6432 standard. Designed with elastische Dämpfungsringe/-platten beidseitig cushioning, a male thread piston-rod end, and an M12x1,25 pneumatic connection, it functions within an operating pressure of 1.2 to 10 bar using dried compressed air, lubricated or unlubricated, across an ambient temperature range of -20 to 80 °C. This unit achieves a theoretical force of 24.6 N at 6 bar advance stroke and features a wrought aluminium alloy cover, high alloy non-corrosive steel cylinder barrel and piston rod, NBR and TPE-U(PU) seals, and a corrosion resistance classification CRC 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.
