Festo
5211903
Round cylinder DSNU-S-12-50-P-A-MQ
The Festo 5211903 is a double-acting industrial component featuring a 12 mm piston diameter and a 50 mm stroke with an M6 piston rod thread. It operates on compressed air within a pressure range of 0.15 MPa to 1 MPa (1.5 bar to 10 bar) and incorporates elastic cushioning rings at both ends with an end-position impact energy of 0.07 J. Built with a piston, piston rod, and cylinder barrel structural design, the unit delivers a theoretical retracting force of 50.9 N and advancing force of 67.9 N at 6 bar while supporting any mounting position and position sensing via proximity switch.

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.
