DSNU-20-20-PPV-A – High-Performance ISO Round Cylinder
The Festo DSNU-20-20-PPV-A is a double-acting pneumatic round cylinder with a 20 mm stroke and 20 mm piston diameter, built for precision-controlled motion. It features pneumatic cushioning that is adjustable at both ends, allowing fine-tuned deceleration of the piston rod to reduce shock loads and extend equipment life.
This cylinder complies with ISO 6432 and CETOP RP 52 P, ensuring global compatibility and standardization. It supports working pressures from 1 to 10 bar, and delivers robust performance—up to 188.5 N forward stroke force and 158.3 N return stroke force at 6 bar pressure. The M8 piston rod thread, G1/8 port, and optional mounting make it easy to install across various machine designs. The construction uses a high-alloy stainless steel piston rod, anodised aluminium body, and is RoHS-compliant, making it suitable even in cleanroom or corrosion-sensitive environments.
Applications of Festo DSNU-12-70-P-A in Real Industrial Settings
The DSNU-12-70-P-A model is ideal for linear actuation where moderate force and longer stroke are required in tight or compact installations. For example, in automatic fixture clamping, this cylinder can be used to apply consistent pressure over multiple cycles without losing alignment. In conveyor diverter mechanisms, it provides quick and repeatable movement for directing parts to different paths based on inspection results.
The integrated proximity switch compatibility enables precise feedback to PLCs, which is crucial in automated systems. Maintenance engineers benefit from its reliable operation and low replacement frequency, while engineering students can study the dynamics of pneumatic actuation through this widely used model. Its adjustable cushioning is particularly valuable in applications that require smooth stopping—such as in robotic end-effectors, small presses, or part-feeding arms.
Whether used in training labs or high-speed industrial machinery, this cylinder balances simplicity and performance, earning its place in both entry-level and advanced automation setups.
