Product Information

Full details

The Festo DSNU-40-25-P-A is a double-acting pneumatic cylinder designed for industrial automation. It is ideal for applications requiring reliable linear motion and precise positioning, offering a theoretical advancing force of 752.9 N at 6 bar. A key benefit is its integrated magnetic piston for position sensing, simplifying system integration. However, it requires a compatible pneumatic system and proper mounting to function correctly.

FAQs

What is the theoretical advancing force at 6 bar?

The theoretical advancing force at 6 bar is 752.9 N.

Does this cylinder require lubrication?

The DSNU series is designed for operation without lubrication if using standard filtered compressed air. However, if your system incorporates oil-free air, it may be suitable. Consult Festo's general guidelines for pneumatic cylinder lubrication.

How does the magnetic piston work?

The magnetic piston has an integrated magnet that can be detected by external proximity sensors placed along the cylinder's path. This allows the control system to know the piston's position at any given time.

What is the purpose of the elastic cushioning?

Elastic cushioning rings at the end of the stroke absorb the impact of the piston, providing a smoother, quieter stop and reducing wear on the cylinder and connected components.

Can I use this cylinder for applications requiring a longer stroke?

No, this specific model has a fixed stroke length of 25 mm. For longer strokes, you would need to select a different Festo cylinder model with the required stroke.

What type of compressed air should be used?

It is recommended to use clean, dry, and filtered compressed air. For optimal performance and longevity, consider air that meets ISO 8573-1 standards. Lubricated air may be used if the system is designed for it.

What is the operating pressure range?

The typical operating pressure range for this type of cylinder is from 1.5 bar to 10 bar.

Troubleshooting

Cylinder does not extend or retract.

Check air supply pressure and connections. Ensure control valves are functioning correctly and directing air to the appropriate ports. Verify no external obstructions.

Slow or weak movement.

Inspect air lines for leaks or restrictions. Ensure sufficient air pressure. Check if the load exceeds the cylinder's force capacity. Clean or replace air filters.

Cylinder does not stop at the intended position.

Verify that the proximity sensor is correctly positioned and functioning. Check sensor wiring and compatibility with the control system. Ensure the magnetic piston is aligned with the sensor.

Excessive noise or vibration at stroke ends.

Ensure elastic cushioning is functioning. Check if the cylinder is properly mounted and aligned. Reduce air pressure if operating above the recommended range for the load.

Air leaks from cylinder seals.

Inspect the cylinder body and end caps for damage. If leaks persist, the seals may need replacement, indicating potential internal wear. Contact support if internal seals fail.

Pros and Cons

Pros

  • Reliable and durable construction for industrial use.
  • Integrated magnetic piston simplifies position detection.
  • Elastic cushioning reduces operational noise and extends lifespan.
  • Self-adjusting features minimize maintenance needs.
  • Generates significant force for its size (752.9 N advancing at 6 bar).

Cons

  • Requires a compressed air supply and control system.
  • Stroke length is fixed at 25mm, limiting application flexibility.
  • Mounting hardware is not included and needs to be sourced separately.
  • Performance is dependent on air pressure and quality.
  • Suitable primarily for linear motion, not rotational.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely mount the cylinder using appropriate Festo-compatible mounting accessories (e.g., flanges, foot mounts) ensuring alignment with the intended motion path. Verify correct orientation for the application.
  2. Pneumatic Connections: Connect the compressed air lines to the appropriate ports (P1 and P2) on the cylinder. Ensure correct port identification for double-acting control.
  3. Position Sensing: If using position sensing, connect a compatible proximity sensor to detect the magnetic piston at desired stroke positions.
  4. Air Supply: Connect to a clean, dry, and regulated compressed air supply (typically 1.5 to 10 bar).

Compatibility:

  • Requires a compatible pneumatic control system (solenoid valves, air lines).
  • Compatible with standard pneumatic fittings.
  • Proximity sensors for magnetic piston detection should be compatible with the cylinder's magnetic field strength and type.

Care:

  • Periodically inspect air connections for leaks.
  • Ensure the compressed air supply is filtered and lubricated (if recommended by the overall system design) to prevent premature wear.
  • Keep the cylinder body clean; wipe with a dry or slightly damp cloth. Avoid abrasive cleaners.
  • Monitor performance for any signs of degradation and address promptly.
