Festo
The Festo 156518 is a double-acting industrial component featuring a 20 mm piston diameter and a 25 mm stroke with an internal M5 piston rod thread at one end. Operating via compressed air compliant with ISO 8573-1:2010 [7:4:4], it functions within a pressure range of 1 bar to 10 bar and an ambient temperature range of -20 °C to 80 °C. Position sensing is achieved through a proximity switch, while elastic cushioning rings at both ends absorb 0.14 J of impact energy.
