Pneumatic ISO cylinder for linear motion

The Festo DSNU-20-300-PPS-A is a standard ISO pneumatic cylinder built for linear actuation in automation systems. It delivers a 300 mm stroke within a 20 mm bore size for precise movement control. Supplied new in a single pack, it carries part number 559280 for exact identification. The unit is finished in red and classified as test equipment by the manufacturer.

Suited for fixed-stroke automation tasks

This cylinder suits engineers designing machinery that requires a defined 300 mm travel distance and 20 mm bore diameter. It is not for applications needing adjustable stroke lengths, different bore sizes, or non-ISO mounting standards. Buyers requiring hydraulic operation or electric actuator integration should look elsewhere. The three-year parts and one-year labour coverage supports long-term industrial use.

300 mm stroke length defines fit

The 300 mm stroke is the critical dimension that determines whether this cylinder fits the mechanical design. A shorter or longer required travel makes this specific model unsuitable for the build. The 20 mm bore and ISO profile are fixed characteristics that must match the existing mounting pattern. Verify the stroke requirement against the machine layout before ordering.

Questions about this item

How do I mount the DSNU-20-300-PPS-A ISO cylinder and what alignment step is often missed?

Secure the cylinder using its standard ISO mounting interfaces, then verify piston-rod alignment with the load path; misalignment causes premature seal wear and uneven stroke motion.

Which wear parts of the 559280 cylinder need replacement after the three-year parts coverage ends?

Plan to replace the piston seals, rod wiper and cushioning seals once the three-year parts period expires; these items degrade with cycle count and operating pressure.

What is the first performance limit reached when the DSNU-20-300-PPS-A runs continuous 300 mm strokes at full pressure?

Sustained full-pressure cycling typically hits the cushioning capacity first, causing end-of-stroke impact before seal friction or air consumption become limiting factors.
