Hydraulic servo-cylinder SLZ series

rotarypistonfor mechanical testing

Servo cylinder
Servo cylinders convert hydraulic energy (controlled by servovalves) into mechanical energy. They are available in axial and torsional types: axial servo cylinders transfer load via linear displacement while torque is generated by rotation in torsional units. These cylinders are designed for use in servo-hydraulic testing machines and test systems for static and dynamic material and component testing.

Performance and specifications
All axial servo cylinders comply with strict amplitude and frequency specifications across various response curves. High sensitivity, very high piston speeds, mechanical strength and economical design result from accumulated experience, technical know-how and manufacturing quality.
