Product Information

Full details

This Festo DSNU-25-70-PPS-A pneumatic cylinder is designed for industrial automation professionals seeking reliable linear actuation. Its key benefit is the self-adjusting end-position cushioning, which simplifies setup and ensures smooth operation across varying loads and speeds. A potential caveat for some users might be the specific G 1/8 pneumatic connection, requiring compatible fittings. This double-acting cylinder offers a 25mm bore, 70mm stroke, and supports up to 10 bar operating pressure, featuring a magnetic piston for position sensing and a durable design for long service life.

Extended Product Information

FAQs

What is the theoretical force of this cylinder?

At 6 bar operating pressure, the theoretical advancing force is approximately 294.5 N.

How does the self-adjusting cushioning work?

The cushioning automatically adapts to changes in load and speed at the end of each stroke, ensuring a smooth stop without manual adjustment.

Can I use this cylinder with non-standard compressed air?

It is recommended to use clean, dry compressed air. If lubrication is required by your system, ensure it is compatible with Festo components.

What is the maximum stroke length?

The cylinder features a 70mm stroke length.

Does this cylinder come with sensors?

The cylinder is designed with a magnetic piston to allow for external position sensing. Sensors are typically sold separately and must be compatible with magnetic pistons.

What is the weight of the cylinder?

The cylinder weighs approximately 315g.

What type of pneumatic connection does it use?

The pneumatic connection is a G 1/8 thread.

Troubleshooting

Cylinder does not extend or retract

Check compressed air supply pressure and flow. Verify valve operation and ensure pneumatic connections are secure and leak-free. Confirm the piston is not obstructed.

Jerky or inconsistent movement

Ensure the air supply is clean and dry. Check for internal wear or damage. Verify that the self-adjusting cushioning is functioning correctly and not set to an extreme.

Air leaks from the cylinder

Inspect seals and O-rings for damage. Check pneumatic port connections for tightness. If leaks persist, the cylinder may require service or replacement.

Position sensor not detecting piston

Ensure the sensor is compatible with magnetic pistons and is correctly positioned adjacent to the cylinder barrel. Check sensor wiring and power supply.

Pros and Cons

Pros

  • Self-adjusting cushioning reduces setup time and improves performance.
  • Magnetic piston allows for easy and accurate position monitoring.
  • ISO 6432 compliance ensures broad compatibility.
  • Robust design promotes longevity and reliability.
  • Suitable for applications requiring precise linear motion control.

Cons

  • G 1/8 pneumatic connection may require specific adapters.
  • Theoretical force calculation requires known operating pressure.
  • Maximum operating temperature of +80°C might be limiting for extreme environments.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely mount the cylinder using appropriate brackets and fixings, ensuring alignment with the load path.
  2. Pneumatic Connection: Connect the G 1/8 port to your compressed air supply using compatible fittings. Ensure the air supply is clean and dry.
  3. Actuation: Connect the control valves to the cylinder ports for extension and retraction.
  4. Sensor Integration (Optional): If using position sensing, mount compatible magnetic field sensors near the cylinder barrel to detect the piston's position.

Compatibility:

  • Pneumatic Standards: Compliant with ISO 6432.
  • Operating Pressure: Compatible with compressed air systems operating between 0.5 bar and 10 bar.
  • Temperature Range: Suitable for ambient temperatures from -20°C to +80°C.
  • Fittings: Requires G 1/8 threaded fittings.

Care:

  • Air Supply: Use filtered and lubricated compressed air (if required by your system) to prevent contamination and wear.
  • Environment: Avoid exposure to corrosive substances or extreme dust.
  • Inspection: Periodically check for leaks and secure mounting.
  • Cleaning: Wipe down the exterior with a dry or slightly damp cloth. Avoid harsh solvents.
