Servo-hydraulic Rotary Actuators
Servo-hydraulic rotary actuators are used to excite parts and complete test structures with static and dynamic test forces. To meet these requirements and achieve absolute duplication precision, the rotary actuators are equipped as standard with hydro-static radial and axial bearings. These special bearings significantly improve the service life and the frequency behaviour of the rotary actuators.
The rotary drives are equipped as standard with the following accessories:
- Mounting block for servo valves
- Servo valves on request 2 or 3 stage, various manufacturers by arrangement
- Smoothing memory in forward and reverse in the rotary angle measuring system (analogue/digital) mounted on the rotary shaft
- Preparation for the building of differential pressure transducers
Special features:
- Hydrostatic pocket bearing (radial / axial) of the rotor shaft
- Integrated rotation angle measuring system
- Optical rotation angle display

from 500 to 32 KNm
Continuous operating pressure maximum:
280 bar
Swing angle maximum:
± 60°
