Festo
The Festo 557116 is a double-acting industrial component built on the ISO 21287 norm with a 1 5/8-inch piston diameter, a 2.5-inch stroke, and a profile barrel structural design featuring a piston rod with an internal 5/16-24 UNF-2B thread at one end. Operating on compressed air according to ISO 8573-1:2010 [7:4:4] within a pressure range of 14.5 psi to 145 psi, this unit delivers a theoretical advancing force of 170 lbf and a retracting force of 154 lbf at 6 bar. It incorporates elastic cushioning rings at both ends, position sensing via proximity switch, and a moderate corrosion resistance class rating of CRC 2 for ambient temperatures between -4 °F and 176 °F.
