Customized hydraulic cylinder - Special solutions Hydraulic cylinders - custom-tailored for you
With decades of expertise in developing and manufacturing special solutions, our development team is always there for you. Whenever possible, we use minor modifications of our modular standard elements to adapt them to your requirements as cost-effectively as possible. If necessary, we can even develop entirely new solutions for you.
If simple adjustments don't suffice, we'll design complete customized hydraulic cylinders to suit your requirements. Whether you need cylinders with special damping, for dosing, injection, weight compensation or oscillation. Here you can see some examples for such special solutions.
70 % of our sales come from special solutions, that speaks for itself!

Extensions and adaptations for customized cylinders Changing the fluid
Different applications require different fluids. The food industry requires oils that are not harmful to the human body, steel mills need fire-resistant fluids. The customized hyraulic cylinders are designed accordingly with suitable seals and coatings. Examples of fluids:
Extensions and adaptations for customized cylinders Changing the material
The choice of material depends on the application in question and is customized to your individual requirements. For example:
Stainless steel for the food industry
Non-magnetic steel for the medical industry
Aluminum saves weight
Tough-at-sub-zero-temperatures steel for cold regions/environments
Individual constructions Screw-in cylinders
Hydraulic cylinders are mounted mechanically before establishing a hydraulic connection using hoses or pipes. A space-saving alternative are screw-in cylinders built into stepped bores using a stepped cylinder housing. Insertable in a block, this cylinder is usually integrated in a machine and protected from external influences. The advantages:
Small construction volume
Easy installation without screwed fittings
Individual constructions Hydraulic cylinder with anti-torsion mechanism
Piston rods in hydraulic cylinders are usually secured against torsion by means of mounting parts. If the rod is not fixed, torsion can occur. Even small external torques can be enough, and even the surface structure of the piston rod can cause torsion over the stroke. Mechanical devices can prevent this, even for very high torques. We select the best version for your application.
Individual constructions hydraulic cylinders as guide pillar
The solution for a space-saving combination of linear movement and an exact guide: the guide pillar with the hardened surface and an integrated hydraulic cylinder. This allows precise guidance and movement of loads coupled with the piston rod without subjecting the cylinder to side loads.
For weight compensation or to obtain a resilience effect, sometimes initial loads must be applied to the test objects. This is a job for customized hydraulic cylinders with a pressurized protection tube. Drive and hydraulic spring are combined in one component part.
Additional pressure from an accumulator is applied to the free piston rod, the so-called protection tube side, of a double-rod hydraulic cylinder. Thus, the working area A3, determined by the rod diameter, acts as a "protection tube spring". With its two chambers A1 and A2, the hydraulic cylinder works in addition to this continuous hydraulic force.
Hydraulic cylinders with working areas of the same size are convenient for dynamic movement. Synchronous cylinders are the solution for constricted spaces or long-stroke test tasks. Their length corresponds to that of cylinders with one-side piston rods. A large rod, in which a smaller rod is moving, transfers the force to the outside. This creates two working areas of the same size, A3 for extension and A2 for retraction.
The multi-channel rotary feedthrough offers a solution for the transfer of fluids between a fixed and a rotating assembly. These are particularly used in machines and other precise, fast-rotating systems. The fluid is fed into rotating channels and passes through these into the rotating body.
