Festo
177778
Profile cylinder DNC-1 1/4"-2"-P
The Festo 177778 is a double-acting industrial component featuring a 1 1/4" piston diameter, a 2" stroke, and a male 3/8-24 UNF-2A piston rod thread. Built on a profile barrel design with flexible cushioning rings at both ends, this unit operates on compressed air within a pressure range of 0.6 to 12 bar and supports an ambient temperature span of -20 to 80 °C. It provides a theoretical retracting force of 415 N at 0.6 MPa, a CRC 2 moderate corrosion resistance classification, and functions in any assembly position.
