Festo
The Festo part number 8165664 is a double-acting industrial component featuring a 125 mm piston diameter, a 125 mm stroke, and an M27x2 external piston rod thread conforming to ISO 15552. Constructed with a piston, piston rod, and profile barrel design, this unit operates within a pressure range of 0.02 MPa to 1 MPa (0.2 bar to 10 bar) using compressed air according to ISO 8573-1:2010 [7:4:4]. It is equipped with adjustable pneumatic cushioning at both ends, providing a 45 mm cushioning length and 3.3 J impact energy absorption in the end positions, while delivering a theoretical retracting force of 6881 N at 6 bar. Position sensing is achieved via a proximity switch, and the assembly supports any mounting position across an ambient temperature range of -20 °C to 80 °C.
