A linear electro-mechanical actuator () preferably for water cutting, makes it possible to significantly improve the working conditions of the actuator (), so as to optimize its load capacity and increase the working life of the actuator (), and makes it possible to reduce the risk of breakage or damage of the actuator () following loss of control of the movement aimed at producing the force applied by the actuator ().

Linear electro-mechanical actuator, preferably for water cutting

A linear electro-mechanical actuator, includes a containment structure (), one or two pushers facing each other (), a nut () rotatable about an axis (X) driven by a driving force, a screw shaft () inserted in the nut (), connected to the pushers and interconnected with the nut () via a helical recirculating ball coupling (), and an anti-rotation mechanism () acting on the screw shaft () to prevent the screw shaft () from rotating about the axis (X). The anti-rotation mechanism () includes a pair of fixed guide bars (), coupled in a sliding fashion with the screw shaft () and extending along a direction parallel to the axis (X) and spaced from the axis (X).
