Festo
5211909
Round cylinder DSNU-S-12-150-P-A-MQ
The Festo 5211909 is a double-acting industrial component featuring a 12 mm piston diameter, a 150 mm stroke, and an M6 piston rod thread with a structural design comprising a piston, piston rod, and cylinder barrel. It operates on compressed air according to ISO 8573-1:2010 [7:4:4] 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. Certified for cleanroom use to ISO Class 5 and rated for moderate corrosion stress with a CRC of 2, this unit delivers theoretical forces of 50.9 N retracting and 67.9 N advancing at 6 bar across any mounting position.
