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.

Want to keep your mechanical applications on the straight and narrow? Reach for this round pneumatic cylinder from Festo. The streamlined three-component system includes a piston, piston rod and cylinder barrel, which move together in linear lockstep. It's a double-acting device, so uses compressed air to drive the piston back and forth with precision. Taking on smaller loads and low-speed applications is easy, thanks to flexible polymer cushioning rings at both ends, which integrate directly into the main piston to absorb energy. When the pressure's on, the cylinder handles challenges up to 10 bar.

• Long service life due to non-corrosive, high-alloy stainless steel material
• Short 80mm stroke for quick, controlled movements
• Threaded G1/8 port connection makes it widely compatible
• Reliable operation in harsh industrial conditions with temperatures between -20°C and +80°C

• Hospital machinery
• Laboratories
• Factory equipment

As you can mount the cylinder in any position, using accessories, it's a versatile option.

This cylinder fits neatly into your setup with dimensions of 212 (L) x 27mm (D) and a piston diameter of 20mm.
