Abstract
The electromechanical actuator cylinder provides a casing, an actuation rod mounted to be movable longitudinally relative to the casing, an electric motor provided with a stator and with a rotating rotor shaft, and a mechanism for converting a rotational movement of the rotor shaft into a linear movement in translation of the actuation rod. The actuator cylinder includes at least one roller bearing for guiding the rotor shaft in rotation relative to the casing and providing at least one row of rolling elements. An inner raceway for the row of rolling elements of the bearing is formed directly on the rotor shaft.
