Compact Double-Acting Cylinder for Space-Constrained Automation
The Festo ADN-50-35-A-P-A (manufacturer ID 8178336) is a pneumatic cylinder engineered for applications where installation space is limited but performance cannot be compromised. With a 50 mm piston diameter and a 35 mm stroke, this unit delivers a practical balance of force and travel in a compact envelope. Its double-acting operation provides controlled motion in both extend and retract directions, making it suitable for tasks such as clamping, feeding, or positioning in assembly lines and specialized machinery.
The cylinder's design follows ISO 21287, ensuring dimensional interchangeability with other compact cylinders that meet the same standard. This simplifies replacement and integration into existing systems, reducing downtime during maintenance or retrofits. The piston rod features an external thread (M12x1.25), allowing straightforward attachment of couplings or tooling.
Material Selection and Environmental Suitability
Festo specifies high-alloy steel for the piston rod and anodized wrought aluminum alloy for both the cylinder barrel and covers. These materials provide good corrosion resistance, rated at CRC 2 for moderate corrosion stress, which suits typical industrial environments with occasional exposure to moisture or mild contaminants. The unit is RoHS-compliant, and seals are made from TPE-U (PUR), offering resilience in dynamic applications.
Operating temperature ranges from -20°C to 80°C, and the cylinder can be mounted in any position, giving design flexibility. The medium must be compressed air per ISO 8573-1:2010 [7:4:4], and while oil lubrication is permissible, it is only required if the cylinder will be used in a lubricated system later. This allows clean, oil-free operation if desired.
Cushioning and Sensing for Reliable Operation
End-position cushioning is provided by elastic rings or pads at both ends. This feature absorbs impact energy up to 1 J, reducing noise and mechanical stress on the cylinder and connected components. The result is smoother deceleration, which contributes to longer service life and consistent cycle times.
Position sensing is supported via proximity sensors, enabling precise monitoring of piston position for automation control. This is critical for applications requiring feedback for sequencing or safety interlocks. The cylinder's design includes a piston rod at one end, and the mounting options include through-holes, internal threads, or accessories, allowing adaptation to various machine frames.
Performance Data for System Design
At a supply pressure of 6 bar, the theoretical advancing force is 1178 N, while the retracting force is 1057 N due to the rod area. These values help engineers calculate the cylinder's capability for pushing or pulling loads. The moving mass is 220 g, and the total product weight is 711 g, which is relevant for dynamic calculations and energy consumption estimates.
The pneumatic connection is G1/8, a common port size that simplifies piping. Operating pressure range is 0.6 to 10 bar, offering flexibility for various air supply systems. The cylinder also meets LABS (PWIS) conformity VDMA24364-B1/B2-L, making it suitable for use in paint shops or other applications where silicone-free components are required.
Integration and Maintenance Considerations
When integrating the ADN-50-35-A-P-A into a machine, consider the mounting style that best fits your structure. The optional through-hole or internal thread mounting simplifies installation without needing extra brackets. The cylinder's compact dimensions allow it to fit into tight spots, but always verify that the stroke and force meet your application's requirements.
For maintenance, the elastic cushioning components may wear over time and should be inspected periodically. The use of standard seals and materials ensures that replacement parts are readily available. Because the cylinder is designed for moderate corrosion environments, avoid exposing it to aggressive chemicals or prolonged submersion. With proper air preparation and regular checks, this Festo cylinder offers dependable performance in a wide range of automated systems.
