Up to
less volume and weight
Whether in highly efficient presses, in harsh underground environments or in heavy-duty cranes in mining – wherever enormous forces need to be controlled with pinpoint accuracy, ACONA hydraulic cylinders are in use.
Developed, calculated and manufactured at our site in Herzogenrath near Aachen, we combine state-of-the-art engineering with manufacturing expertise gained from over 60 years of market experience – and set new global benchmarks for performance, service life and sustainability through innovations such as our deep-R technology.
At our factory in Herzogenrath near Aachen, design, manufacturing and quality assurance are closely interlinked – all under one roof. This ensures that new designs can be implemented and optimised directly on the machines. This minimises coordination efforts and significantly accelerates the entire development process without compromising precision or quality.
Thanks to short coordination paths, we can react during the design phase when requirements change or new ideas arise. In an emergency, this saves you valuable days – sometimes even weeks – in the project schedule and reduces the costs that would arise from lengthy adjustment loops or external coordination.
Because all our experts are in-house, special materials, complex designs or special coatings can be implemented without any problems. This means you receive exactly the customised hydraulic cylinder that meets your requirements in the shortest possible time – without compromising on quality or delivery date.
With specialised machinery and modern test benches, we guarantee consistently high manufacturing quality. Each assembly is subjected to strict checks immediately after processing in accordance with the design requirements – without the need for transport or logistics.
Our location near the RWTH Aachen University lets us keep in close touch with the most famous institutes at the technical university. A lot of our employees are graduates of the university or work with us as working students, either in operations or as part of their final thesis. This helps us stay up to date and discuss and implement our own development ideas at the highest level.
The finite element method (FEM) is the key that allows us to precisely adapt the load capacity of your hydraulic cylinder to your specific application during the design phase. Many manufacturers, on the other hand, still rely on conservative calculation approaches. Such methods only take local stress peaks, notch and weld seam effects into account in a rough manner – the result is oversized cylinders that are unnecessarily heavy and cost-intensive.
With FEM analysis, we map real load conditions in detail and identify potential risks or buckling hazards before a prototype is created. This is particularly important for high-safety applications such as hydraulic cylinders for cranes, where the safety verification against buckling must be absolutely reliable. Precise analysis allows wall thicknesses and material usage to be optimised with pinpoint accuracy: weight and resource consumption are reduced, while load-bearing capacity and stiffness are increased exactly where it is structurally necessary.
On request, we can provide you with comprehensive strength verification in accordance with all relevant standards – an argument that convinces testing organisations and your internal stakeholders alike. Since FEM simulation enables reliable predictions, many time-consuming prototype loops are no longer necessary. Development times and costs are reduced measurably. It is precisely this combination of standard-compliant safety, planning transparency and fast time-to-market that is the reason why more and more customers are specifically choosing ACONA.
What is deep-R?
deep-R is a surface hardening process developed by us that specifically targets the biggest weak point of conventional hydraulic cylinders – the weld seam. Micro-pores are compacted, compressive residual stresses are introduced and potential crack nuclei are plastically deformed, while we smooth the surface and increase its hardness.
This results in significantly higher fatigue strength, which enables us to reduce wall thicknesses, achieve higher operating pressures and drastically extend the service life of our cylinders – without compromising safety.
For the development of deep-R, we combined proven processes with state-of-the-art calculation methods in collaboration with Wirsing Industrial Research. The effectiveness of our process was then thoroughly tested and empirically confirmed by the Machine Tool Laboratory (WZL) at RWTH Aachen University.
Our deep-R process offers you the following advantages:
Up to
less volume and weight
Up to
increase in performance
Up to
longer service life
The reinforced weld seams allow wall thicknesses to be significantly reduced. This means that a cylinder with higher performance can fit into a much smaller space.
Slimmer cylinders use up to 35% less material and thus valuable resources. Lower raw material consumption and a doubling of service life measurably reduce your CO₂ footprint.
Existing cylinders can be improved retrospectively during maintenance using our deep-R process. This allows us to increase performance reserves and extend the remaining service life without costly remanufacturing.
Research network
Thanks to close cooperation with universities and institutes, the latest findings on materials and innovative processes flow directly into your projects. This results, for example, in press cylinders that can complete millions of stroke cycles, as well as hydraulic cylinders for cranes that guarantee buckling resistance and corrosion resistance for decades.
Interdisciplinary team
Our experts from various fields, ranging from mechanical engineering to materials technology, work closely together from the initial sketch to production. Their combined expertise enables us to develop hydraulic cylinders that can handle extreme temperature ranges, highly dynamic load changes and abrasive media with equal ease.
Agile project management
Close cooperation with the customer and the proximity of design, manufacturing and quality assurance ensure that your project always stays on schedule. This not only shortens the delivery time of your cylinder, but also minimises change loops and measurably reduces development costs. At ACONA, we see ourselves not only as a supplier, but also as your development partner.
This ensures that every customer receives exactly the hydraulic cylinder that precisely meets their specific requirements and supports their systems with maximum efficiency, safety and cost-effectiveness throughout their entire life cycle.
The combination of engineering expertise, state-of-the-art manufacturing ‘Made in Germany’ and a consistently research-driven approach to innovation gives our hydraulic solutions a competitive edge. The proximity of design, production and quality assurance shortens decision-making processes, reduces costs and ensures maximum precision.
Right from the design stage, we use extensive FEM analyses to eliminate oversizing, increase safety and accelerate your time to market. In addition, our proprietary deep-R technology creates leaner, more powerful and significantly more durable cylinders – scientifically tested and retrofittable at any time.
In short: we supply you with exactly the hydraulic cylinder that meets your specific requirements, reduces your carbon footprint and reliably secures your plant operation for years to come.
