We project and realize high performance oleodynamic Servo Actuators. The design of each type of actuator is tailored on the Costumer's specific needs: our Servo Actuators are particularly suitable in Industry, for Research purposes, and in testings which require maximum precision.
We are the very first users of our Servo Actuators, since we adopt them in a wide range of applications in our Lab, especially for performing high precision Static Tests, and realiable Dynamic/Fatigue Tests.
All of our Servo Actuators have high working precision, robustness, and compactness. The vast majority has double symmetric stem and include an integrated displacement transducer. The Full Scale generally ranges between 2 and 1,500 kN at 210 bar.
In the following, we show some Servo Actuators of our project and realization:
Hydrostatic Servo Actuator
Actuator for static, dynamic, and fatigue tests, with very high speed and accuracy. Its main characteristic is the presence of hydrostatic Supports and near null Friction. A non-hydrostatic version can be realized too, adopting low friction seals and preserving the following features:
Very compact size, both in length and in external diameter
Possibility to add a front or read flanging
Possibility to add a front and/or read articulated junction
Coaxial displacement transducer integrated inside the stem
This actuator is particularly adapt for use in fixed Test Benches, for instance when testing hydraulic shock absorbers, in which case it is important to grant loading precision at high frequencies and high speeds.

Integrated Servo Actuator
Actuator for static, dynamic, and fatigue tests, with very high dynamic response and allowing for rapid and practical install. Among its main features:
Extremely small size, much smaller than the other types of Actuator
Large diameter double stem, with very low friction supports and very high resistance to lateral loads
Possibility to add a front or read flanging
Possibility to add a front and/or read articulated junction
Coaxial Displacement Transducer, integrated inside the stem
Integrated Load Cell, within the outer stem
Frontal Spherical joint, integrated inside the Load Cell
This actuator is particularly adapt for use in multi axial Test Benches and to perform light duty fatigue tests, being very resistant to induced strong lateral loads. Very compact and lightweight, it allows to exert a Traction and Compression Force which is c.a. 1,000 times greater than its own weight.

Multivalve Servo Actuator
This actuator is tailored to testings with high dynamic response, very high speed and considerable instant oil flow. It features:
Possibility to install from 1 up to 4 servo valve, which work in parallel to achieve the most high flows
Very low friction sealings, even at low pressure
Anti-friction guides with composite/ceramic coated stem grant very accurate performaces, invariable in time and in extremely heavy working conditions.
Very compact size, both in length and in external diameter
Possibility to add a front or read flanging
Possibility to add a front and/or read articulated junction
Coaxial Displacement Transducer, integrated within the stem
Particularly useful for use in those Test Benches which require very high operating speeds and high oil flows.

Pivoting Servo Actuator
Pivoting Actuator designed for static, dynamic, and fatigue tests. While moving axially, it has no constaint on lateral movements. In other words, this Servo Actuator exerts loads without torque reactions. Other features include:
Very compact size, both in length and in external diameter
Possibility to add a front or read flanging
No need for any articulated junction
Together with an hydrostatic spherical joint, it achieves a system with very high axis loads, with no friction junctions; schematically: a load rod with perfect joints
It is especially useful whenever it is necessary to grant the actuator to be completely free to move laterally, without any parasite load usually generated in spherical joints when loaded.
