Festo: Engineering Motion with Global Precision
Festo is a globally respected manufacturer of automation components, known for its advanced pneumatic and electric motion systems. With German engineering at its core, Festo products are designed for consistent performance, durability, and global standard compliance. Across India, Festo cylinders are widely used in factories and workshops due to their easy integration, long life, and reliability in demanding industrial environments.
DSNU-25-125-PPV-A: Long-Stroke Cylinder with Adjustable Pneumatic Cushioning
The Festo DSNU-25-125-PPV-A is a double-acting round cylinder built to ISO 6432 standards, offering a 125 mm stroke and a 25 mm piston diameter. It delivers up to 294.5 N of advance force and 247.4 N on return at 6 bar pressure. The key feature of this model is its adjustable pneumatic cushioning at both ends, allowing engineers to fine-tune the end-position damping according to the load and speed—minimizing impact and extending component life. With a G1/8 pneumatic port, M10x1.25 piston rod thread, and proximity switch compatibility for position detection, this cylinder is designed for smooth integration into automation systems. It is built using anodised aluminium and high-alloy stainless steel, making it corrosion-resistant and suitable for cleanroom Class 6 operations.
Where It’s Used: Precision Adjustment for Long Reach Applications
The DSNU-25-125-PPV-A is a great fit for motion tasks that require longer stroke lengths and precise end-position control—such as mechanical part pressing, automated clamping, or material shifting operations in conveyor systems. The manually adjustable cushioning is especially valuable when machine conditions vary or when soft stopping is required to prevent wear or misalignment. For maintenance engineers, it means flexibility and fine control without replacing components. For engineering students, this cylinder showcases how thoughtful mechanical tuning improves the stability and performance of pneumatic systems. It’s a strong choice for machines that need reliability over a longer distance with minimal vibration or shock at end positions.
