DSNU-25-100-PPS-A: Long Stroke Cylinder with Self-Adjusting Cushioning
The Festo DSNU-25-100-PPS-A is a double-acting round cylinder with a 25 mm piston diameter and an extended 100 mm stroke. It features self-adjusting pneumatic cushioning at both ends, allowing the cylinder to automatically adapt to speed and load conditions—offering smoother deceleration and reduced mechanical stress. It delivers up to 294.5 N forward force and 247.4 N return force at 6 bar. The build includes a high-alloy stainless steel piston rod and anodised aluminium housing, providing corrosion resistance and cleanroom compatibility (Class 6). With a G1/8” pneumatic port, proximity switch support, and RoHS compliance, this model meets modern industrial standards and simplifies installation in diverse environments.
Where It’s Used: High Flexibility, Minimal Tuning Required
The DSNU-25-100-PPS-A is ideal for dynamic automation tasks where the load or speed may vary throughout the operation. Typical use cases include material pushers, machine guarding systems, automated stops, and linear conveyors. The self-adjusting cushioning helps absorb impact without needing manual adjustment—saving time during installation and reducing long-term maintenance. This makes it particularly useful in production lines that run different product batches or operate at variable speeds. Maintenance engineers appreciate the reduced downtime and consistent performance, while students and junior technicians gain insights into how automation components can intelligently adapt to working conditions.
