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:
  • Mineral oils
  • Silicone oils
  • Bio-degradable oils
  • Brake fluid

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
Customized to your individual requirements, like hanging the material

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

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.

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.

Custom hydraulic cylinder with pressure protection tube

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.

Synchronous cylinders

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.

rotary feedthrough

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. Possible fields of application:
  • Coolant supply in tool spindles
  • Supply of hydraulic cylinders on rotating portals
