REALISTIC SIMULATION OF LOAD STATES

Servo-cylinders convert hydraulic energy (controlled by servo-valves) into mechanical energy. They differ in their types of loading: For the axial servo-cylinder (SLZ) loading is defined in terms of translation, and for the torsional servo-cylinder (SDZ) it is in rotation. Our servo-cylinders are implemented in servo-hydraulic test machines and test systems for static and dynamic testing of materials and components.

All axial servo-cylinders satisfy the most stringent technical requirements related to amplitude and frequency for different curve characteristics. Excellent response behavior, extremely high piston speed, durability and economy are the product of experience, know-how and quality.

Custom Designs

Besides standard applications it is also possible to implement custom designs. This involves implementing a modular layout of standard components together with specially designed components.

Joint assembly of two servo-cylinders as an elevating platform; the servo-cylinders have hydrostatic bearings and transverse reinforcement.
