Festo
The Festo 557142 is a double-acting industrial component featuring a 2 1/2-inch piston diameter and a 1.5-inch stroke built on the ISO 21287 norm. This unit utilizes a profile barrel with a piston rod at one end having an external 1/2-20 UNF-2A thread, operating within a pressure range of 14.5 psi to 145 psi using compressed air as per ISO 8573-1:2010 [7:4:4]. Position sensing is achieved via a proximity switch, while elastic cushioning rings at both ends manage an impact energy of 0.959 ft-lbf alongside theoretical forces of 393 lbf retracting and 420 lbf advancing at 6 bar.
