FAQs

What is the maximum operating pressure for this cylinder?

The maximum operating pressure for the DSNU-20-50-P-A is 10 bar.

Is this a single or double-acting cylinder?

This is a double-acting cylinder, meaning air pressure is used to move the piston in both directions.

What kind of lubrication does this cylinder require?

The cylinder is designed for use with compressed air that meets ISO 8573-1:2010 standards, which generally assumes a clean, dry, and potentially lubricated air source.

Can I adjust the cushioning on this model?

No, this model features fixed elastic cushioning and does not support manual adjustment.

What is the piston rod thread size?

The piston rod is equipped with an M8 thread.

What is the stroke length?

This specific model has a stroke length of 50 mm.

Troubleshooting

Cylinder is leaking air from the ports

Check the pneumatic fittings at the G1/8 connection for proper seating and ensure the tubing is cut squarely.

Cylinder sluggish or erratic movement

Verify the quality of compressed air and ensure it meets ISO 8573-1:2010 standards; check for moisture or contaminants in the lines.

Unexpected impact at end of stroke

Reduce the operating pressure or install an external flow control valve to regulate the cylinder's speed during the end-of-stroke approach.

Pros and Cons

Pros

  • High durability for industrial environments
  • Smooth operation due to elastic cushioning
  • Standardized mounting dimensions per ISO 6432
  • Wide operating temperature tolerance

Cons

  • Requires high-quality filtered compressed air
  • Not suitable for applications requiring extreme heavy-duty shock loads
  • Fixed cushioning cannot be adjusted manually

Setup, Compatibility & Care

To install, ensure the cylinder is securely mounted using compatible ISO 6432 hardware. The pneumatic connection uses a standard G1/8 inch port, and the piston rod is equipped with an M8 thread for standard clevis or rod eye attachments. Care instructions include using only ISO 8573-1:2010 quality compressed air to avoid internal corrosion or seal degradation. Regularly inspect the piston rod for debris or contaminants that might damage the rod seal during the stroke cycle.
