Festo
170128
Standard cylinder DSNU-20- -PPV-A-CT
The Festo part number 170128 is a double-acting industrial component featuring a 20 mm piston diameter and a stroke length of 10 to 320 mm with an M8 piston rod thread. Built with a piston and piston rod design structure conforming to ISO 6432, it operates on dried compressed air, lubricated or unlubricated, across a working pressure range of 1 to 10 bar and an ambient temperature range of -20 to 80 °C. This unit incorporates adjustable pneumatic cushioning at both ends (PPV), position detection for proximity sensors, a copper- and PTFE-free variant (CT), and Germanischer Lloyd authorization, delivering theoretical forces of 158.3 N on the return stroke and 188.5 N on the advance stroke at 6 bar.
