The Festo DSNU-25-80-P-A pneumatic cylinder is a compact, industry-standard ISO 6432–compliant double-acting pneumatic linear actuator designed for consistent motion control across manufacturing automation, assembly machinery, and material handling systems. Built to exacting standards with durable materials and precise engineering, this unit delivers reliable, repeatable performance in demanding industrial environments.
Overview
The DSNU-25-80-P-A is part of Festo’s established DSNU series of pneumatic cylinders. This Festo DSNU-25-80-P-A model features a 25mm bore, 80mm stroke, and operates across a 1–10 bar (0.1–1 MPa) pressure range, making it suitable for light to medium-duty applications. The round-body design with elastic cushioning on both the piston rod and cylinder barrel minimizes impact shock and extends component life. Male-threaded rod end (M10×1.25) provides secure mechanical attachment options for linkages, load cells, or custom fixtures.
Key Features
- ISO 6432 certification — global interchangeability and performance standards
- Double-acting design — extends and retracts under controlled pneumatic pressure
- Elastic cushioning — integrated cushioning rings on piston rod and cylinder barrel reduce impact and vibration
- M10×1.25 male-threaded rod end — drop-in mechanical interface for mounting rods, linkages, or external fixtures
- G1/8 pneumatic connection — standard metric threaded port for quick-connect or push-in tubing
- Stainless steel and aluminum construction — corrosion-resistant barrel and high-strength structural integrity
