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.

Go through the motions with precision using this pneumatic cylinder from Festo. Its clever 3-in-1 design features a piston, piston rod and cylinder barrel. Connection ports at each end enable linear back-and-forth movement using compressed air. The unit tackles the demands of heavy loads thanks to adjustable pneumatic cushioning positioned at both ends of the barrel to absorb excess energy. Both the piston rod and cylinder barrel are made from high-alloy stainless steel that stands up to corrosion damage, so you get a long service life. The housing is anodised, wrought aluminium alloy that you can count on for strength and durability.

• Withstands high-pressure environments up to 10 bar
• Suitable for heavy-duty industrial settings, thanks to an operating temperature range between -20°C and +80°C
• Weighs in at 366.8g, so minimises strain on your setup

• Factory automation
• Packaging machinery
• Transportation equipment

This double-acting pneumatic cylinder can move in both directions with a high degree of accuracy. It has a 250mm stroke length combined with a 20mm piston diameter, making it ideal for heavy lifting or lowering of medium to large loads.

The cylinder has a standard G1/8 pneumatic connection with a male piston rod thread.
