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 device that pulls its weight in your air-powered system? Turn to this pneumatic cylinder from Festo. It's a double-acting type that drives loads in two directions, so you can be sure of controlled movements in your automated equipment. A stroke length of 200mm means it stretches to meet the demands of long-range tasks. Cushioning on each end absorbs energy from the rod's movement to cut down on wear and noise, making it a smooth operator.

• High-alloy steel piston and barrel for resistance to corrosion and impact
• M5 pneumatic connection for compatibility with standard parts
• Performs reliably at temperatures between -20°C and +80°C for use in harsh environments

• Robotics systems
• Industrial automation
• Processing machines
• Packaging lines

With the help of a handy mounting kit (121-5566) that clamps the barrel, it's a doddle to fit a proximity sensor anywhere along the body of this unit. For versatility, the cylinder is compatible with proximity sensors in the SMT and SDBT series.
