Hydraulic cylinder repair

Like all components subjected to high loads, hydraulic cylinders are not immune to wear.
With our deep-R technology, we can double the lifespan of a hydraulic cylinder. However, in machines where cylinders operate under constant stress, certain assemblies will eventually need to be replaced.

With over 70 years of experience, we are true experts in hydraulic cylinders – ready to repair your cylinder even if it is not an ACONA product.
In addition to professional hydraulic cylinder repair, we also assist you in identifying failure causes and analyzing potential improvement.

By utilizing advanced FEM analyses (Finite Element Analysis), we can accurately investigate critical stress zones and pinpoint structural weaknesses.
Our many years of experience in design, analysis, and hydraulic cylinder maintenance form the foundation for a deep technical understanding of possible failure mechanisms – from material fatigue and seal failure to unfavorable force application.
This comprehensive approach provides the basis for sustainable improvement of your components.

Get your hydraulic cylinder repaired

In most cases, repairing a hydraulic cylinder contributes more to sustainability than completely replacing it. Our company follows a structured approach to ensure quality.

In addition to repair work, we use our technical expertise to make targeted improvement suggestions. If materials or designs are no longer state of the art, we identify this at an early stage and highlight optimization options – for more durable and efficient solutions.

Hydraulic cylinder repair: the most common causes

A hydraulic cylinder is subjected to constant hydraulic and mechanical loads. High levels of stress lead to wear and damage.

The most common causes include contamination in the hydraulic oil, which attacks seals and surfaces, as well as increased lateral loads that can result in uneven wear of the guiding elements. Corrosion is also a frequent type of damage, particularly in cases of insufficient surface protection or extended periods of downtime.

Typical wear parts of a hydraulic cylinder include:

Common hydraulic cylinder failures include:

Hydraulic cylinder refurbishment

It is not possible to define in general terms when a hydraulic cylinder must be repaired, because this depends heavily on its specific application.

Some cylinders are in operation around the clock, others only a few times per month, and there are cylinders that may be used only once or twice during the entire service life of the machine.

What we can say with certainty, however, is this: even if manufacturers estimate the service life of a laundry cylinder at around ten years under daily operation, in practice the seals usually need to be replaced earlier.

These are the hydraulic cylinders we can repair for you:

Long-lasting solutions from a single source

Whether standard cylinders or custom solutions – at ACONA you get more than just a repair. We think ahead, carry out thorough analysis and optimize wherever it is possible and reasonable. In this way, we not only ensure the proper functioning of your hydraulic cylinder, but, if desired, also improve its performance and service life.
