Festo
This Festo 557127 industrial component is a double-acting compact cylinder built on the ISO 21287 norm featuring a 2-inch piston diameter, a 3-inch stroke, and a 1/2-20 UNF-2A external piston rod thread at one end. Operating within a pressure range of 14.5 psi to 145 psi (1 bar to 10 bar) using compressed air per ISO 8573-1:2010 [7:4:4], the unit incorporates elastic cushioning rings at both ends and allows position sensing via a proximity switch. It delivers a theoretical advancing force of 265 lbf and a retracting force of 238 lbf at 6 bar, with an ambient temperature tolerance of -4 °F to 176 °F and a moderate corrosion resistance class (CRC 2).
