Compact Power for Tight Spaces
The Festo ADN-63-35-I-P-A (manufacturer ID 8178659) is a double-acting compact cylinder designed for automation tasks where installation space is limited but performance cannot be compromised. With a 63 mm piston diameter and a 35 mm stroke, it delivers a theoretical force of 1870 N advancing and 1750 N retracting at 6 bar. This makes it suitable for clamping, pressing, or short-stroke transfer operations in assembly lines, packaging machinery, and specialized machine building.
Weighing just 921 g and featuring a moving mass of 236 g, the cylinder contributes to low inertia and faster cycle times. Its compact footprint, combined with the ability to mount in any position, simplifies integration into existing systems.
Built to Standards, Ready for Sensing
The ADN-63-35-I-P-A conforms to ISO 21287, ensuring interchangeability and predictable performance across installations. The cylinder is prepared for proximity sensors, allowing straightforward position feedback for sequence control. The piston rod has an internal thread (M10), and the pneumatic connection is G1/8, matching common port sizes for quick hookup.
Operating pressure ranges from 0.6 to 10 bar, and the unit handles ambient temperatures from -20°C to 80°C. The medium is compressed air per ISO 8573-1:2010 [7:4:4], with oil lubrication possible if required for downstream processes.
Durable Materials and Cushioning
Elastic cushioning rings at both ends absorb impact energy up to 1.3 J, reducing noise and mechanical stress. This cushioning extends service life and protects the workpiece and machine structure. The cylinder body is made of smooth-anodized wrought aluminum alloy, while the piston rod uses high-alloy steel for strength and wear resistance. Seals are TPE-U(PUR), and flange screws are steel. All materials are RoHS-compliant, and the product meets LABS (PWIS) conformity VDMA24364-B1/B2-L, making it suitable for paint shops and other sensitive environments.
With a corrosion resistance class of 2 (moderate stress), the cylinder can handle typical industrial atmospheres without special coatings.
Selection and Integration Considerations
When specifying the ADN-63-35-I-P-A, verify the stroke length and force requirements against your application. The 35 mm stroke is fixed, so ensure it matches the needed travel. The cylinder can be mounted using through-holes, internal threads, or accessories, offering flexibility in design. For position sensing, choose compatible proximity sensors and mount them in the sensor slots (not included).
Because the unit is double-acting, it requires controlled air supply on both ports. The G1/8 connections are suitable for 6 bar nominal operation, but check your system's pressure and flow to achieve the desired speed and force. The moving mass of 236 g should be considered in dynamic calculations for high-speed applications.
Practical Benefits for Automation Engineers
The ADN-63-35-I-P-A reduces design effort with its standardized dimensions and multiple mounting options. Its lightweight construction eases handling during installation and maintenance. The elastic cushioning minimizes impact forces, which is critical for fragile workpieces or high-cycle operations.
For procurement teams, the cylinder's compliance with ISO 21287 and RoHS ensures broad acceptance in global equipment builds. The availability of over 350 variants in the ADN series means that if this exact model does not fit, a close alternative likely exists—but for this specific stroke and bore, the ADN-63-35-I-P-A offers a balanced combination of force, compactness, and durability.
