Festo
The Festo 156778 is a double-acting industrial component featuring a 20 mm piston diameter, a 40 mm stroke, and a square piston rod at one end that provides protection against torsion and guiding. It operates within a pressure range of 1 bar to 10 bar using compressed air according to ISO 8573-1:2010 [7:4:4] and incorporates elastic cushioning rings at both ends for 0.14 J of impact energy absorption. Designed with a moderate corrosion resistance class of CRC 2 and an ambient temperature range of -20 °C to 80 °C, this unit delivers a theoretical force of 188 N advancing and 141 N retracting at 6 bar.
