Festo
Engineered to ISO 21287 standards, this Festo 557169 double-acting industrial component features a 3-inch piston diameter, a 2.5-inch stroke, and a 1/2-20 UNF-2B internal thread on the single-end piston rod. It operates with compressed air within a pressure range of 14.5 psi to 145 psi and a temperature range of -4 °F to 176 °F, incorporating elastic cushioning at both ends and provisions for position sensing. The profile barrel design achieves a moderate corrosion resistance class of CRC 2 and delivers theoretical forces of 636 lbf retracting and 678 lbf advancing at 6 bar.
