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.

Set your equipment in motion with this pneumatic cylinder from Festo. It delivers the linear action needed to clamp, position and eject objects. To improve the accuracy of your processes, this is a double-acting unit that uses compressed air to drive both the thrust and return strokes. At only 292mm long with a stroke of 160mm, the device is a sure fit for systems where space is at a premium. As it's made from high-alloy stainless steel, it takes chemical and environmental contamination in its stride.

• Cushioning at both ends dampens noise and limits impacts for boosted durability
• Weighs only 302g to put little strain on systems
• Performs dependably in temperatures between -20°C and +80°C

• Automotive industry
• Industrial packaging and assembly processes
• Medical equipment
• Railway applications

As part of a pneumatic system, a cylinder needs to hold pressure for optimal performance. This unit comes with tough NBR seals, so you can be sure it stays airtight.

You can mount it in any position that's best for your system, so it's a versatile choice.
