Festo
The Festo 156517 is a double-acting industrial component featuring a 20 mm piston diameter and a 20 mm stroke, operating via compressed air within a pressure range of 1 bar to 10 bar. Designed with elastic cushioning rings at both ends, an internal piston rod thread of M5, and position sensing via proximity switch, this unit supports any mounting position and permits operation with oil lubrication. It achieves a theoretical advancing force of 188 N and a retracting force of 141 N at 6 bar while withstanding a moderate corrosion stress rating of CRC 2 and ambient temperatures from -20 °C to 80 °C.
