Festo
549970
Standard cylinder DNGL-2 1/2"- -PPV-A
The Festo part number 549970 is a double-acting industrial component featuring a 2 1/2" piston diameter, an adjustable stroke range from 1 to 500 mm, and a square piston rod with a male UNF5/8-18 thread designed for torque protection. Built on ISO 15552 standards with CRC 2 corrosion resistance, it operates on dried compressed air at pressures from 0.6 to 10 bar across ambient temperatures of -20 to 80 °C, delivering a theoretical force of 1,870 N on the advance stroke and 1,682 N on the return stroke at 6 bar. This model includes dual-end adjustable pneumatic cushioning (PPV) over a 23 mm cushioning length, integrated position detection for proximity sensors, and an arbitrary assembly position with an added weight of 60 g per 10 mm of stroke.
