Compact Actuation for Tight Spaces
The Festo ADN-25-35-I-PPS-A (manufacturer ID 8178885) is a double-acting pneumatic cylinder designed to meet the demands of modern automation where space is at a premium. With a 25 mm piston diameter and a 35 mm stroke, this unit delivers a practical balance of force and travel in a compact envelope. Its small footprint simplifies machine layout, allowing engineers to position actuation closer to the work point without sacrificing performance. The cylinder conforms to ISO 21287, ensuring dimensional consistency and interchangeability across compliant systems.
Performance and Control Features
Engineered for precise and repeatable motion, the ADN-25-35-I-PPS-A operates within a pressure range of 1.5 to 10 bar. At 6 bar, it produces a theoretical advancing force of 295 N and a retracting force of 247 N, sufficient for a wide range of clamping, pushing, and positioning tasks. The self-adjusting pneumatic end-position cushioning absorbs impact energy up to 0.3 J over a cushioning length of 3.5 mm, reducing noise and mechanical stress. This feature not only smooths operation but also extends the service life of the cylinder and associated machine components.
The cylinder is equipped with an internal thread on the piston rod (M6) and a pneumatic connection of M5, facilitating straightforward integration with standard fittings and tooling. Its design includes provisions for proximity sensors, enabling reliable end-position detection for automated control sequences.
Durable Construction for Industrial Environments
Reliability in continuous operation is a key consideration for procurement and maintenance teams. The ADN-25-35-I-PPS-A is built with a barrel and covers made of wrought aluminum alloy, anodized for corrosion resistance. The piston rod is crafted from high-alloy steel, and seals are made from TPE-U(PUR), ensuring robust performance under moderate corrosion stress (CRC 2). The unit is RoHS-compliant and meets LABS (PWIS) conformity per VDMA24364-B1/B2-L, making it suitable for use in paint and coating applications where silicone-free materials are required.
With an ambient temperature range of -20°C to 80°C, this cylinder can operate in diverse thermal environments. Its cleanroom classification (Class 6 per ISO 14644-1) further broadens its applicability in controlled manufacturing settings.
Flexible Mounting and Integration
Installation flexibility is a major advantage of the ADN-25-35-I-PPS-A. It can be mounted in any orientation, and offers multiple mounting options: through-holes, internal threads, or using dedicated accessories. This adaptability simplifies machine design and retrofitting. The cylinder's moving mass is only 53 g, and its total product weight is 263 g, contributing to low inertia and responsive operation in high-cycle applications.
As part of the Festo automation ecosystem, this cylinder integrates seamlessly with other Festo components, reducing engineering effort and ensuring system compatibility. Its compact size and performance characteristics make it a practical choice for assembly fixtures, pick-and-place units, and other material handling applications where space and reliability are critical.
Selection Considerations
When specifying the ADN-25-35-I-PPS-A, engineers should verify that the operating medium is clean, dry compressed air per ISO 8573-1:2010 [7:4:4]. While oil lubrication is possible, it must be continued if used initially. The cylinder's theoretical forces provide a baseline for sizing, but actual force output will vary with supply pressure and system losses. For applications requiring position sensing, the cylinder is prepared for proximity sensors, but sensors must be ordered separately. The unit's corrosion resistance class (CRC 2) is suitable for moderate industrial environments; for harsher conditions, additional protection may be necessary.
Overall, the Festo ADN-25-35-I-PPS-A offers a combination of compactness, durability, and performance that aligns well with the needs of modern automation engineers seeking efficient and dependable actuation solutions.
