Festo
549951
Tie rod cylinder DNG-4"- -PPV-A-S2
The Festo 549951 is a double-acting industrial component featuring a 4-inch piston diameter, a stroke length configurable from 1 to 2,000 mm, and a UNF3/4-16 male piston rod thread designed according to ISO 15552. Operating at a working pressure of 0.6 to 10 bar on dried compressed air, this unit achieves a theoretical force of 4,712 N on the advance stroke and 4,418 N on the return stroke at 6 bar. It incorporates adjustable pneumatic cushioning at both ends with a 30 mm cushioning length, position detection for proximity sensors, and an S2 through piston rod variant while operating within an ambient temperature range of -20 to 80 °C.
