Hydraulic cylinders for the marine industry need to be able to function in a harsh environment and under extreme conditions


With many years of experience and the production of a large number of hydraulic cylinders for the marine industry, FJERO is a strong partner.

Quality and durability ensure optimal operation

Harsh and extreme conditions place huge requirements on making the right choice of both components and materials. Wind, weather and seawater continuously affect the daily functioning of applications, which is why corrosion and wear will be an additional strain for the hydraulic cylinder that performs important functions.

Long periods of inactivity without financial loss

At FJERO we are heavily focused on the total costs – and therefore also on designing the optimal solution for your applications. The starting point is to ensure that your hydraulic cylinders also function without problems even after the equipment hasn’t been used for a long period at sea. If the cylinder fails when it is finally to be used, this will run up large operating losses – precisely because the cylinders often work in open sea environments with difficult access conditions for unplanned services and repairs.

Focus on the high reliability of maritime hydraulic cylinders

We achieve a high level of reliability for our hydraulic cylinders by using components that require minimal maintenance. This applies to the choice of an optimal sealing system, bearings, fasteners, sensors, piston rod quality and much more besides. In addition to the high quality of the technical components, the service treatment is just as important if the finished cylinder is to be assured high uptime and a long lifetime – and therefore a better operating economy.

Standard or custom-made cylinders for the marine industry

In general, we base these on FJERO’s own F1 cylinder, which is DNV.GL type approved. Most of our marine customers have some very specific requirements and wishes for their cylinders. However, as their working functions are extremely different in terms of both handling and load, FJERO is therefore specialised in custom-made solutions.

F1 cylinder with standard type approval – perfect for the marine industry

Besides DNV.GL type approval, FJERO’s F1 cylinders can also be supplied with material certificates and pressure test certificates. The F1 cylinder is also offered with other third-party approvals such as ABS, Lloyd´s, RMRS, Bureau Veritas, RINA, CCS and many others. The F1 cylinder thus covers most requirements in a maritime environment.

If certificates and traceability on the cylinder and the materials used are not required, you can benefit from using our F2 cylinder. Our F2 cylinders are manufactured in the same high quality as our F1 cylinders.

Many fastening and combination possibilities

We can accommodate all types of wishes for fastenings:
• Spherical bearing
• Spherical composite bearing
• Adjustable spherical composite bearing
• Trunnion
• Front flange
• Rear Flange
• Piston rod flange
• Clevis
• Fixed eye
• Fixed eye with bronze liner
• Threaded rod end
• Special fastener according to the customer’s wishes

By combining the different fastenings, we can meet all your requirements.
