DSNU-25-250-PPV-A: Precision Cylinder with Adjustable Cushioning for Long Strokes
The DSNU-25-250-PPV-A is a double-acting round pneumatic cylinder with a 25 mm piston diameter and a 250 mm stroke, making it ideal for extended motion applications. Built according to ISO 6432 standards, it generates up to 294.5 N of forward force and 247.4 N on return at 6 bar operating pressure. What makes this model versatile is its adjustable pneumatic cushioning at both ends—allowing engineers to fine-tune piston deceleration for smoother stopping and reduced impact. The cylinder features a G1/8 pneumatic connection, M10x1.25 piston rod threading, and optional proximity switch support for position feedback. It is manufactured using high-alloy stainless steel and anodised aluminium, ensuring RoHS compliance, corrosion resistance, and suitability for Class 6 cleanroom environments.
Where It’s Used: Tuned Control for Long-Distance Linear Motion
The DSNU-25-250-PPV-A is perfect for automation tasks that involve long travel distances with the need for custom damping control—such as in conveyor section actuators, fixture positioning arms, or machine doors. The adjustable cushioning gives engineers the flexibility to optimize motion for different weights and speeds, which helps reduce mechanical wear and noise. Maintenance teams value the manual adjustability, while engineering students learn how precise pneumatic control enhances machine life and process stability. In any setup requiring smooth motion and controlled stopping over long strokes, this model delivers exactly what industrial systems need—performance, adaptability, and trust.
