Festo DSNU series round pneumatic cylinders with flexible cushioning rings 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 P type flexible cushioning pneumatic cylinders absorb energy directly via flexible cushioning rings which are integrated into the main piston. This energy absorbing method makes these cylinders ideal for small load and low speed applications.

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.

Keep your assembly line rolling along smoothly with this round pneumatic cylinder from Festo. It's a long-stroke type with a 100mm stroke length and a 12mm piston diameter. This makes it a good choice for lifting or lowering objects on a conveyor belt to keep production running without a hitch. Cushioning at either end of the cylinder is on hand to minimise equipment noise and vibration. Thanks to its high alloy steel piston rod, you can rely on the unit's resistance to corrosion in humid settings. This metal is also hardwearing, assuring you of an extended service life in harsh operating conditions.

• Suitable for demanding pneumatic systems, thanks to its broad operating pressure range between 1.5 and 10 bar
• Simple round design offers quick and easy assembly
• Can be mounted in any position to best suit your setup
• Compatible with lubricated or non-lubricated compressed air for versatility

• Robotics systems
• Automotive manufacturing
• Breweries
• Hospital equipment

The unit has polymer end-position cushioning that produces minimal friction. This helps to reduce wear and extends the unit's service life. As the cushioning doesn't need adjustment, you benefit from reduced maintenance.
