Application-Specific Design for Demanding Environments
The Festo ADN-50-70-I-PPS-A (manufacturer ID 8178341) is a double-acting pneumatic cylinder engineered for applications that require both reliability and precise motion control. With a 50 mm piston diameter and 70 mm stroke, this ISO 21287-compliant cylinder delivers a theoretical advancing force of 1178 N and retracting force of 1057 N at 6 bar, making it suitable for medium-duty pushing, pulling, clamping, and lifting tasks in automated assembly, packaging, and material handling systems.
Its corrosion resistance class (CRC) 2 rating indicates moderate corrosion stress capability, while the use of high-alloy steel for the piston rod and anodized wrought aluminum alloy for the barrel and covers ensures durability in humid or mildly corrosive settings. The cylinder is RoHS-compliant and meets LABS (PWIS) conformity VDMA24364-B1/B2-L, which is critical for paint and finishing lines where silicone-free operation is required.
Precision Sensing and Smooth Operation
For applications requiring accurate position feedback, the ADN-50-70-I-PPS-A is designed to work with proximity sensors. The cylinder body is optimized for sensor mounting, allowing straightforward integration of position sensing without custom brackets. This capability is essential for automated cycles that depend on confirming end-of-stroke or intermediate positions.
The cylinder features self-adjusting pneumatic end-position cushioning with a cushioning length of 6 mm. This system automatically adapts to load and speed changes, reducing impact energy (up to 2.8 J in end positions) and minimizing mechanical stress on the cylinder and connected components. The result is smoother deceleration, less noise, and extended service life even at higher cycle rates.
Flexible Mounting and Integration
Installation flexibility is a key advantage of this model. The ADN-50-70-I-PPS-A offers multiple mounting options: through-hole, internal thread, or using accessories. This versatility allows engineers to choose the most suitable method for their machine frame, whether it's direct bolting, threaded attachment, or using standard mounting kits. The piston rod end is internally threaded (M10), enabling simple connection to tooling or load-bearing elements.
With a compact design conforming to ISO 21287, the cylinder can replace older, bulkier units without major redesign. The G1/8 pneumatic connection is industry-standard, simplifying piping integration. The cylinder can be mounted in any position, and its operating pressure range of 1 to 10 bar provides flexibility for various supply pressures.
Material Quality and Maintenance Considerations
Festo has selected materials to balance performance and longevity. The cylinder barrel and covers are made of anodized wrought aluminum alloy, offering good wear resistance and a lightweight structure (product weight 864 g). The seals are TPE-U (PUR), known for their resilience and compatibility with compressed air per ISO 8573-1:2010 [7:4:4]. The flange screws are steel, ensuring robust fastening.
Note that while the cylinder can operate with oil lubrication, it is also suitable for non-lubricated operation if the medium is clean and dry. The moving mass is 250 g, which contributes to responsive motion. Ambient temperature range of -20°C to 80°C covers most indoor industrial environments.
Practical Selection Criteria
When specifying this cylinder, consider the following:
- Force requirements: Verify that the theoretical forces at your operating pressure meet the application's load demands, accounting for friction and dynamic effects.
- Mounting style: Choose from through-hole, internal thread, or accessory-based mounting based on your machine's structural constraints.
- Sensing needs: If position feedback is required, ensure proximity sensors are compatible with the cylinder's sensing slots.
- Environmental factors: CRC 2 is suitable for moderate corrosion stress; for harsher conditions, consider additional protection or alternative models.
- Air quality: The operating medium must comply with ISO 8573-1:2010 [7:4:4] to maintain seal integrity and performance.
By matching these parameters to your system requirements, the ADN-50-70-I-PPS-A can provide a dependable, long-lasting actuation solution.
