Festo
The Festo 177779 is a double-acting industrial component featuring a 3-inch stroke and a 1 1/4-inch piston diameter with a 3/8-24 UNF-2A male piston rod thread. Built on the ISO 15552 standard, this profile barrel design operates within a pressure range of 0.06 to 1.2 MPa using compressed air according to ISO 8573-1:2010 [7:4:4] and includes flexible cushioning rings at both ends. It delivers a theoretical retracting force of 415 N at 0.6 MPa, supports any assembly position, and maintains moderate corrosion resistance under ambient temperatures from -20 to 80 °C.
