Festo
The Festo 1646780 is a double-acting industrial component featuring an 80 mm piston diameter, a 320 mm stroke, and an M20x1.5 external piston rod end conforming to ISO 15552. Operating within a pressure range of 0.04 MPa to 1.2 MPa utilizing compressed air per ISO 8573-1:2010 [7:4:4], it incorporates adjustable pneumatic cushioning at both ends, position sensing via proximity switch, and a structural design comprising a piston, piston rod, tie rod 1, and cylinder barrel. Rated for an ambient temperature range of -20 °C to 80 °C and moderate corrosion stress (CRC 2), this variant delivers a theoretical retracting force of 2721 N at 6 bar with 1.8 J of impact energy in the end positions.
