Festo DSNU series round pneumatic cylinders with adjustable pneumatic cushioning at both ends of the actuator barrel. Featuring a stainless-steel piston rod within a 3-component system that provides excellent running performance and long service life. These double acting pneumatic actuators have dual connection ports for compressed air to be applied for advancing and retracting the piston rod in a linear motion. An extensive range of accessories makes it possible to install the DSNU cylinders virtually anywhere.

The DSNU PPV type adjustable cushioning pneumatic cylinders are equipped with a special cushioning piston as an extension to the main piston. This pneumatic cushioning builds up an air cushion to absorb energy in the end positions, building up and exhausting air in a targeted fashion. This energy absorbing method makes these cylinders ideal for medium to heavy loads and high-speed applications.

• Conforms to ISO 6432 providing standardised metric mounting dimensions
• Stainless steel piston rod with a threaded connector
• Wide range of stroke length and bore size variants that can be configured to suit a broad range of applications
• Long service life
• Double acting operation

The DSNU series pneumatic round actuators conform to ISO 6432 standards allowing them to be mounted in any position to suit the required application. The ISO 6432 standard establishes metric mounting dimensions for cylinders providing interchangeability of commonly used hydraulic and pneumatic cylinders. Optional mounting accessories provide further flexibility allowing the cylinder to be attached with a swivel bracket for free movement, foot mounted for support under high loads or combined with other actuators to give a wider range of movement.

Need a pneumatic cylinder that can move loads back and forth? Reach for this double-acting option from Festo. It uses compressed air to extend and retract its piston, so you get accuracy with every stroke. Adjustable cushioning is on hand to absorb impact from the movement of the rod, helping to keep wear and noise to a minimum. As the piston rod and barrel are made of high-alloy steel, they stand up to impact and corrosion in harsh industrial environments. NBR and TPE-U seals prevent leakage to ensure your pneumatic system doesn't run out of steam.

• Wide operating pressure range between 1 and 10 bar for versatility
• Performs reliably in temperatures between -20°C and +80°C for use in demanding environments
• Standard M5 pneumatic connection makes it a cinch to integrate into your existing system

• Robotics systems
• Processing machines
• Packaging equipment
• Hoists and pulleys

For versatility, you can mount this pneumatic cylinder in any position with the help of a foot (121-4364 or 121-4365) or a clevis foot (121-5632).
