The FESTO 536317 ADN-50-50-A-P-A is a compact pneumatic cylinder designed for industrial automation systems that require reliable linear motion, space-saving installation, and standardized mechanical integration. Official FESTO data identifies this model as ADN-50-50-A-P-A, with a 50 mm stroke, 50 mm piston diameter, double-acting operating principle, and compliance with ISO 21287, which is the core international standard for this class of compact cylinders.
For applications in assembly equipment, packaging lines, transfer stations, fixture actuation, and general machine building, a compact cylinder is often preferred when installation space is limited but the actuator still needs to deliver stable thrust, repeatable movement, and long service life. The ADN series is positioned exactly for that role. This specific version uses a male piston rod thread, supports position detection via proximity switch, and is built for operating pressures from 0.6 bar to 10 bar, giving it a broad usable range in standard compressed-air systems.

Product Weight
A key requirement in your request is product weight. For the ADN-50-50-A-P-A, datasheet-style technical listings corresponding to this exact part number give a basic weight at 0 mm stroke of 540 g and an additional weight of 51 g per 10 mm stroke. For a 50 mm stroke, that gives a calculated product net weight of 795 g. This value is derived as 540 g + (51 g × 5).
Because the currently surfaced official FESTO web snippet does not show the weight line directly, the 795 g figure should be understood as a weight derived from published datasheet-format sources that mirror FESTO technical data for this exact model. That is still a solid working figure for catalog, quotation, and product-description purposes, but I would treat it as a datasheet-derived weight rather than claiming it is pulled from the visible line of the current official product page.
Product Design and Structural Features
The ADN-50-50-A-P-A belongs to FESTO’s compact cylinder family built around ISO 21287 dimensions. That matters because standardization simplifies mechanical replacement, machine design, and long-term maintenance planning. In industrial practice, standardized cylinders reduce redesign work when a machine builder wants predictable mounting geometry or when an end user needs to source a direct equivalent within the same dimensional class. For this model, FESTO explicitly states conformity to ISO 21287, making it a structured industrial component rather than an improvised non-standard actuator.
The cylinder uses elastic cushioning rings or plates at both ends, identified by the A-P-A configuration. This is important because end-position cushioning directly affects service life, noise level, and mechanical shock at the end of stroke. In repetitive automation cycles, uncontrolled piston impact increases wear on the actuator and on the driven mechanism. Elastic end cushioning is not the same as externally adjustable pneumatic cushioning, but for many compact-machine duties it provides a practical balance between simplicity, durability, and installation economy.
The male-thread piston rod end with M12x1.25 thread supports direct integration with clevises, rod eyes, adapters, brackets, or custom tooling. That makes the model suitable for machine designers who want a straightforward link between the cylinder and the moving mechanical assembly. FESTO also specifies the variant as piston rod at one end, which is the classic single-rod compact-cylinder configuration used in a wide range of automation designs.
Why This Cylinder Is Suitable for Industrial Use
The ADN-50-50-A-P-A sits in a useful middle ground. With a 50 mm bore and 50 mm stroke, it is larger and more force-capable than miniature compact cylinders, but still considerably more space-efficient than many traditional profile cylinders with the same bore. This makes it a sensible choice when a machine needs short to medium linear travel with meaningful output force but cannot afford the installation envelope of a longer conventional cylinder body. That conclusion is an engineering interpretation, but it follows directly from the compact-cylinder classification and the published bore and stroke values.
Its double-acting design is also significant. Double-acting cylinders use compressed air to drive motion in both directions, which generally gives more controlled and balanced movement than spring-return alternatives in medium-duty industrial service. That is especially relevant in fixtures, stops, feeders, ejectors, clamping systems, and transfer devices, where both extension and retraction need to be repeatable and not dependent on spring force alone. FESTO explicitly identifies this model as double-acting, confirming that it is intended for those more controlled motion duties.
Installation and Sensing Advantages
FESTO lists the mounting position as optional, which gives machine builders more freedom in system layout. In practice, that means the cylinder can be installed in whichever orientation best suits the mechanism, provided the surrounding application conditions remain within specification. The datasheet-style sources also indicate optional mounting with through-hole, internal thread, or accessories, which reinforces the product’s flexibility in real machine installations.
The model also supports position detection via proximity switch, which is important in PLC-controlled automation. Cylinder sensing is often required for interlocks, sequence control, alarm logic, and confirmation of end position. A compact cylinder that is ready for sensor-based feedback is easier to integrate into modern automated equipment than a purely mechanical actuator with no practical sensing arrangement. FESTO’s official data explicitly confirms proximity-switch-based position detection for this exact model.
Materials and Construction
Published datasheet-format technical listings for this exact model identify the cover material as anodized aluminum, the cylinder barrel as wrought aluminum alloy with smooth anodized finish, the piston rod as high-alloy steel, and the seals as TPE-U (PUR). That material combination is standard for quality pneumatic cylinders intended for industrial service. Aluminum construction helps control weight while maintaining stiffness, and a high-alloy steel piston rod supports wear resistance and stable long-term operation under normal plant conditions.
These material choices also align with the ADN series’ role as a compact but industrially serious actuator family. This is not a lightweight disposable cylinder for low-duty hobby use. The combination of standardized geometry, metal body construction, and industrial sealing system places it firmly in the category of real production-machine components. That is partly interpretive language, but it is grounded in the published materials and construction data.
Practical Performance Value
The 0.6 to 10 bar operating pressure range gives the ADN-50-50-A-P-A strong compatibility with normal industrial compressed-air systems. Many factories operate within a standard pneumatic range where this cylinder can function without special pressure-conditioning requirements beyond standard air preparation. The G1/8 pneumatic connection is also a practical port size for this bore and stroke class, making the cylinder easy to integrate with common fittings and tubing arrangements used in industrial equipment.
The 795 g product weight is also commercially relevant. It indicates a component that is compact for its class, but still substantial enough to reflect a solid mechanical build. For moving assemblies, that weight remains manageable; for fixed installations, it is not excessive; and for compact machine layouts, it is generally acceptable given the 50 mm bore and ISO-standard construction. This makes the actuator suitable for machines that need a balance between strength, compact packaging, and installation practicality.
Typical Application Areas
| Application Area | Why This Model Fits |
|---|---|
| Assembly machinery | Compact body with standardized mounting dimensions |
| Packaging equipment | Reliable double-acting linear motion in limited space |
| Clamping and stopping systems | 50 mm bore supports useful output force |
| Transfer and handling modules | Proximity-switch sensing supports sequence control |
| General machine building | ISO 21287 design simplifies integration and replacement |
These uses are consistent with the published product classification as a compact, double-acting cylinder to ISO 21287 with sensing compatibility and flexible mounting options.
