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.

Ensure your equipment enjoys a smooth run with this pneumatic cylinder from Festo. With its double-action design, it's made to move back and forth – simply apply compressed air to the pair of connection ports and the piston rod will do the rest. This rod fits snugly into the cylinder barrel, with both components made from stainless steel to resist corrosion. To suit your setup, the cylinder can be mounted in any position. Thanks to a standard threaded G1/8 connection, fitting and removal is a snap.

• Integrated elastomer cushioning rings boost efficiency by absorbing energy at both ends of the piston
• Short 125mm strokes ensure accuracy
• Weighs in at 238g, so minimises strain
• Operates reliably in challenging settings with temperatures ranging from -20°C to +80°C

• Medical equipment
• Factory automation
• Chemical plants

Cylinders with cushioning at each end, like this one, are protected against the noise, vibration and potential damage that could otherwise be caused by the piston stopping at each end.

The piston has a diameter of 25mm and slides right into the cylinder's compact external dimensions of 266.5 (L) x 27mm (D).
