Festo
The Festo 557276 is a double-acting industrial component built on ISO 21287 standards featuring a 3-inch piston diameter, a 2-inch stroke, and a profile barrel structural design with a guide rod and yoke for anti-torsion protection. Operating within a pressure range of 1 bar to 10 bar and an ambient temperature span of -4 °F to 176 °F, this unit delivers theoretical forces of 636 lbf retracting and 678 lbf advancing at 6 bar using compressed air per ISO 8573-1:2010 [7:4:4]. It is equipped with elastic cushioning rings at both ends, position sensing capabilities for proximity sensors, and a moderate corrosion resistance class (CRC 2).
