DSNU-20-20-P-A – Compact Cylinder with Reliable Elastic Cushioning
The Festo DSNU-20-20-P-A is a 20 mm stroke, 20 mm piston diameter round pneumatic cylinder designed for light to medium-duty automation tasks. This double-acting cylinder includes elastic cushioning at both ends to absorb impact forces smoothly, reducing wear and extending machine life. Its M8 male-threaded piston rod, combined with G1/8 pneumatic ports, ensures easy integration into standardized systems.
This model conforms to ISO 6432 and CETOP RP 52 P, allowing seamless replacement or compatibility in international setups. It operates efficiently between 1–10 bar, with a theoretical advance force of 188.5 N and return force of 158.3 N at 6 bar. With materials like anodized aluminium for the body and high-alloy stainless steel for the piston rod, it withstands moderate corrosion (CRC Class 2) and meets cleanroom requirements (Class 6). It’s also RoHS-compliant, safe for modern automated environments.
Where Is the DSNU-12-70-P-A Used? – Real-World Applications
The Festo DSNU-12-70-P-A model is used in practical, space-sensitive applications where precise, repetitive linear movement is required. For example, in a packaging line, it may control a pusher arm that moves boxes to the next station. In an electronics assembly setup, it might be used to lift or press components during inspection or soldering processes.
Because it supports position sensing, engineers can easily integrate it into PLC-controlled systems to ensure every movement is tracked and verified. The cylinder's high repeatability, lightweight build, and clean design make it ideal for machines where space and reliability matter. Common users include junior maintenance engineers handling small plant equipment and senior professionals managing automation in fast-paced production lines.
This model strikes the right balance between performance and size—making it a reliable choice in any industry that values precision and durability without overcomplicating the system.
