DSNU-40-70-PPS-A – Technical Overview
The DSNU-40-70-PPS-A is a robust pneumatic round cylinder with a 40 mm piston diameter and 70 mm stroke, designed for medium-duty industrial tasks. It features self-adjusting pneumatic end-position cushioning, which minimizes shock at stroke ends without manual tuning. The advance stroke force is 752.9 N, and the return stroke force is 633.3 N at 6 bar pressure. Built for optional mounting positions, it includes a G1/4 pneumatic port, a M12x1.25 threaded piston rod, and is compatible with position detection sensors. The cylinder is made of high-alloy stainless steel, with seals in NBR and TPE-U(PU), ensuring resistance to moderate corrosion (CRC class 2) and compliance with RoHS. Its lightweight aluminium cover and compact 829 g build make it ideal for tight-space installations.
Application Insights – Festo DSNU-12-70-P-A in Real-World Use
The DSNU-12-70-P-A is commonly selected for applications requiring precise linear movement in a compact footprint. It’s used in automated inspection jigs, small clamping systems, and material transfer arms in industries such as electronics, FMCG, and special purpose machinery (SPM). For example, in a control panel assembly line, it can gently press-fit components without damaging delicate parts. Maintenance engineers value its smooth motion, low air leakage, and reliable cushioning. Engineering students working on automation projects learn core principles of flow control, cushioning behavior, and motion repeatability using this cylinder, making it a practical learning tool as well.
