Model Overview โ DSNU-25-400-P-A Cylinder
The DSNU-25-400-P-A is a double-acting pneumatic round cylinder with a 25 mm piston diameter and an extended 400 mm stroke length, ideal for applications requiring long linear movement. It conforms to ISO 6432 standards and includes elastic cushioning rings/plates at both ends, which reduce impact forces and extend component life. The cylinder uses compressed air (ISO 8573-1:2010 [7:4:4]) as its operating medium and supports position detection via proximity sensors, making it compatible with modern automation systems. With a G1/8 pneumatic connection, male-threaded piston rod, and modular mounting options, itโs easy to integrate into existing setups. Built with high-alloy stainless steel and anodised aluminium, this cylinder is RoHS-compliant and corrosion-resistant, suitable for cleanroom use (up to Class 6) and general industrial environments.
Where DSNU-12-70-P-A is Commonly Used
The DSNU-12-70-P-A is a compact round cylinder favored for its light weight and fast response. In Indian industries, it is commonly found in pick-and-place units, assembly automation lines, and test stations. For maintenance teams, it provides a reliable choice for precise, short-stroke actuation in tight spaces where larger cylinders won't fit. It is especially useful in electronics, plastic molding, and small packaging machines. Engineering students working with pneumatics in college labs can easily understand the basics of motion control using this model, from cylinder cushioning and stroke adjustment to pneumatic circuit design. By studying how this smaller cylinder is applied, learners gain hands-on knowledge that directly translates to real-world industrial setups.
