DSNU-20-P-A – Compact Cylinder for Medium Force Applications
The DSNU-20-P-A is a round cylinder with a 20 mm piston diameter and stroke lengths from 1 mm to 320 mm. Built for double-acting operation, this model uses compressed air and operates reliably between 1 to 10 bar pressure. It features elastic cushioning rings at both ends to reduce impact during stroke transitions, enhancing service life.
With an M8 male-threaded piston rod, G1/8” pneumatic connection, and optional mounting accessories, it offers simple installation in tight machine layouts. The materials—high-alloy stainless steel piston rod and aluminium body—are RoHS-compliant and built for moderate corrosion resistance (CRC Class 2). Its cleanroom compatibility (ISO Class 6) and ability to work between -20°C to 80°C make it suitable for both controlled and workshop environments.
How DSNU-12-70-P-A Helps in Real-World Engineering Scenarios
The DSNU-12-70-P-A round cylinder is often used where precise short-stroke linear motion is required. Imagine an automated filling machine, where a nozzle must lower and return with consistent force—or a parts ejection system, where a gentle push is needed every few seconds. This is where the 70 mm stroke length becomes ideal: long enough to handle common mechanical movements, yet compact for tight spaces.
It integrates well with proximity sensors for position feedback and is highly preferred by maintenance teams due to its low maintenance and easy part replacement. Engineering students exploring pneumatics also use such models to learn stroke control, cushioning behavior, and the importance of clean air supply. It’s not just a cylinder—it’s a trusted component that engineers can rely on across machines, panels, and experimental setups.
