The <\/span>actuators<\/b><\/a>\u00a0Servo-hydraulic linear actuators are the moving elements in a mechanical testing system and are responsible for transmitting both force and displacement to the specimens being tested.<\/span><\/p>

Within our product range, we develop and manufacture hydraulic actuators of different types.<\/span><\/p>

\u00a0<\/p>

What are hydraulic actuators or cylinders and what types are there?<\/strong><\/h2>

A hydraulic cylinder is a <\/span>linear actuator that is used to push or pull a load, or to selectively resist movement under the load, by means of fluid pressure<\/b>.<\/span><\/p>

We design and manufacture servo actuators in two versions: CH4 Series<\/a><\/strong> and\u00a0CH9 Series<\/a>.<\/strong><\/span><\/p>

The CH4 series is specifically designed for static and quasi-static tests up to 3 Hz in continuous operation. The CH9 series is designed for dynamic tests up to 100 Hz.<\/span><\/p>

We will tell you in more detail the characteristics of each one.<\/span><\/p>

Hydraulic Actuator Series<\/b><\/h2>

SERIE CH4<\/b><\/h3>

La CH4 Series<\/a> is characterized by its versatility and reliability<\/b> and are designed to work in static and quasi-static tests, and may occasionally be used in cyclic tests, with a maximum frequency of 10 Hz.\u00a0<\/span><\/p>

Sealing is by low friction, high speed gaskets.<\/span><\/p>

They can be mounted on test benches, forming a testing machine, or on other types of structures, such as test gantries.\u00a0<\/span><\/p>

Through the use of our <\/span>PCD2K control software <\/b><\/a>can work individually or synchronized with other actuators, of the same or any other type.\u00a0<\/span><\/p>

The strength and stroke of this series is adapted in each case to the requirements of the project, starting from the following values:\u00a0<\/span><\/p>

Minimum career:<\/b> 50 mm\u00a0<\/span><\/p>

Minimum load capacity:<\/b> 1000Kgf.\u00a0<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

SERIE CH9<\/b><\/h3>

Dynamic actuators CH9 Series<\/strong><\/a>, <\/span>designed to perform fatigue tests with high precision in force and displacement control.<\/b><\/p>

Hydrostatic type hydraulic servo actuators.\u00a0<\/span><\/p>

From Servosis <\/span>we customize designs<\/b> actuators according to customer requirements in terms of travel, load capacity, type of support, sensors included, etc.<\/span><\/p>

The equipment is designed from the beginning in Servosis, so that we can tailor it to the application without dependence on third parties involved.\u00a0<\/span><\/p>

Pressure sealing system:\u00a0<\/b><\/p>

They are designed so that they do not incorporate sealing gaskets on the piston or on the outlet caps of the piston rods.\u00a0<\/span><\/p>

They have a system of pressure injectors in the outlet collars that keep the stem floating in a film of oil, without friction.\u00a0<\/span><\/p>

High response:\u00a0<\/b><\/p>
