Festo Pneumatic Cylinder - 19212, 20mm Bore, 100mm Stroke, DSNU Series, Double Acting

Get your system moving with this pneumatic cylinder from Festo. Air moves through it, driving the piston rod back and forth to create linear motion. Flexible cushioning rings on both ends are on hand to soften the blow, shielding the rod from impact. As this unit weighs just 258.8g, it doesn't put unnecessary strain on your setup. Thanks to a broad operating temperature range between -20°C and +80°C, it gets on with the job reliably, even in harsh environments.

• G1/8 connection is threaded for hassle-free installation
• Tough high-alloy steel barrel resists impacts and corrosion, for a long service life
• Robust NBR and TPE-U(PU) seals help prevent leakage and maintain an airtight setup

• Aerospace engineering
• Packaging facilities
• Laboratories

A single-acting pneumatic cylinder features one port that air flows through to move the rod. It typically comes with a spring that resets the piston to its original position. With a double-acting cylinder like this one, there are two open ports, so compressed air pushes the rod in both directions, removing the need for a mechanical return system.
