Festo
The Festo 161231 is a double-acting industrial component featuring a 12 mm equivalent piston diameter, a 160 mm stroke, and an M6 piston rod thread with a single-end rod design and an oval piston for torsion protection. Operating on compressed air within a 1.6 to 10 bar pressure range and a -20 °C to 80 °C ambient temperature span, this unit incorporates elastic cushioning rings at both ends and position sensing via proximity switch. It delivers a theoretical retracting force of 51 N at 6 bar, a maximum rotation angle of plus or minus 2.5 degrees, and achieves moderate corrosion resistance under CRC 2 conditions.
