DSNU-20-125-P-A – Technical Highlights
The DSNU-20-125-P-A is a double-acting pneumatic round cylinder built to ISO 6432 standards, offering a 125 mm stroke with a 20 mm piston diameter. It features elastic cushioning rings at both ends, designed to minimize impact forces and reduce wear during stroke reversal. This model operates at 1–10 bar pressure, using clean compressed air according to ISO 8573-1:2010 [7:4:4], and delivers a theoretical advance force of 188.5 N and return force of 158.3 N at 6 bar. The cylinder includes a G1/8 pneumatic port, M8 male-threaded piston rod, and supports position sensing via proximity switches. Made from high-alloy stainless steel and colourless anodised aluminium, it offers moderate corrosion resistance (CRC Class 2), is RoHS-compliant, and is suitable for use in cleanroom Class 6 environments.
Applications of DSNU-12-70-P-A in Industrial and Educational Settings
The DSNU-12-70-P-A is ideal for systems requiring compact but longer linear movement—such as indexing tables, pushing arms, or component feeding mechanisms. Its slim profile allows easy integration in tight spaces, while the reliable cushioning supports smooth operation in repetitive cycles. In Indian factories, engineers prefer this model for its ease of installation and alignment with standard fittings. It reduces the chance of downtime by ensuring consistent force delivery even in variable-load conditions. In technical colleges and skill labs, students use this model to grasp key concepts like stroke force, air pressure behavior, and the impact of cushioning in pneumatic design. The DSNU-12-70-P-A is a perfect balance of simplicity and performance for real-world automation.
