Festo
The Festo part number 557117 is an ISO 21287 compliant double-acting industrial component featuring a 3-inch stroke, a 1 5/8-inch piston diameter, and a 5/16-24 UNF-2B internal piston rod thread on one end. Operating within a pressure range of 14.5 psi to 145 psi (0.1 MPa to 1 MPa), this profile barrel cylinder utilizes elastic cushioning pads at both ends, accommodates any mounting position, and enables position sensing via proximity switches. It delivers theoretical forces of 154 lbf retracting and 170 lbf advancing at 6 bar using compressed air per ISO 8573-1:2010 [7:4:4], with a moderate corrosion resistance class (CRC 2) and an ambient temperature range of -4 °F to 176 °F.
