DSNU-25-70-PPS-A: Built-in Cushioning for Smoother Motion
The Festo DSNU-25-70-PPS-A is a double-acting round cylinder built to international ISO 6432 standards, ensuring global compatibility and consistent performance. It features a 25 mm piston diameter with a 70 mm stroke, delivering up to 294.5 N of forward force at 6 bar pressure. Unlike standard models, it includes self-adjusting pneumatic cushioning at both ends, which automatically adapts to changes in speed and load—reducing wear, noise, and vibration. The piston rod, made from high-alloy stainless steel, ensures durability even in demanding environments. With a G1/8” pneumatic port, corrosion-resistant materials, and cleanroom suitability (ISO Class 6), this cylinder is ready for long-term use in critical applications.
Where It’s Used: Smart Cushioning for Demanding Applications
The DSNU-25-70-PPS-A is ideal for motion tasks that involve varying loads or speeds—common in automated packaging, material handling, or fixture positioning systems. The self-adjusting cushioning eliminates the need for manual tuning, which saves time during installation and reduces the chance of human error. Maintenance engineers value this feature when deploying cylinders across multiple machines with different dynamics. In high-cycle applications, such as automated inspection, pick-and-place, or parts transfer, this model minimizes wear and ensures consistent motion—leading to fewer breakdowns and smoother operation. It's especially useful in industries where precision and low maintenance are equally important.
