Festo
The Festo 1646801 is a double-acting industrial component featuring a 100 mm piston diameter, a 25 mm stroke, and an M20x1.5 piston rod thread conforming to ISO 15552. Built with adjustable pneumatic cushioning at both ends, a 31 mm cushioning length, and a 2.5 J impact energy rating in the end positions, this tie-rod cylinder operates within a pressure range of 0.04 MPa to 1.2 MPa and delivers a theoretical retracting force of 4418 N at 6 bar. It supports compressed air operation per ISO 8573-1:2010 [7:4:4], position sensing via proximity switch, and functions across an ambient temperature range of -20 °C to 80 °C with moderate corrosion stress resistance.
