Product Information
Full details
The Festo DSNU-40-50-PPV-A is a double-acting round cylinder engineered for industrial automation tasks requiring precise movement and reliable force, such as clamping, positioning, or ejecting in manufacturing lines. With a 40 mm bore and 50 mm stroke, it delivers a robust 752.9 N force at 6 bar, making it an excellent choice for demanding mechanical environments. While it offers superior durability through adjustable pneumatic cushioning, users should note that its specialized design requires consistent filtered air supply to prevent seal degradation over time.

FAQs
Can this cylinder be used in high-temperature environments?
Yes, it is rated for a temperature range of -20°C to +80°C.
Does this cylinder require external lubrication?
It is designed to operate with either lubricated or non-lubricated compressed air, though once lubricated, it must remain lubricated to prevent seal issues.
What is the maximum operating pressure?
The maximum operating pressure is 10 bar.
How do I adjust the cushioning?
Use a screwdriver to turn the cushioning adjustment screws located at both end caps to control the air exhaust speed during the final portion of the stroke.
Is the position sensing included?
The cylinder includes a magnetic piston for sensing, but the external proximity sensors must be purchased separately.
What is the force output at 6 bar?
The theoretical force at 6 bar is 752.9 N when advancing.
Troubleshooting
Piston is moving sluggishly or not at all
Check the pneumatic supply lines for blockages, ensure the pressure is at least 1 bar, and verify that the flow control valves are properly opened.
Excessive noise or vibration at the end of the stroke
Adjust the pneumatic cushioning screw (PPV) to increase the damping effect until the movement is smooth.
Magnetic sensor not detecting position
Ensure the proximity switch is correctly positioned on the cylinder body and that it is compatible with the cylinder's magnetic piston.
Pros and Cons
Pros
- High theoretical force output for its compact size
- Adjustable cushioning prevents mechanical shock
- Built-in position sensing via magnetic piston
- Wide operating temperature range for harsh environments
- Long service life due to high-quality Festo engineering
Cons
- Requires clean, lubricated or non-lubricated compressed air
- Sensitive to particulate contamination in air lines
- Not intended for non-pneumatic fluid applications
Setup, Compatibility & Care
To install, mount the cylinder using appropriate Festo-compatible mounting accessories, ensuring the axis is aligned with the load to prevent side-loading. For pneumatic connections, use standard threaded fittings compatible with the cylinder port sizes.
Maintenance Tips:
- Periodically check air lines for leaks or kinks that might cause pressure drops.
- Ensure the compressed air supply is filtered; moisture or debris inside the cylinder can cause internal seals to fail.
- Adjust the cushioning screws only when the system is depressurized or carefully during test cycles to avoid sudden piston movement.
- If the environment is exceptionally dusty, consider installing a protective bellows or shield to prevent grit from entering the piston rod seal.
