Abstract
An electromechanical cylinder contains a casing, an actuating rod mounted so as to be able to move longitudinally relative to the casing, an electric motor provided with a rotating rotor shaft, a mechanism for transforming a rotational movement of the rotor shaft of the electric motor into a linear translational movement of the actuating rod, and at least one bearing for guiding the rotor shaft of the electric motor in rotation relative to the casing and for supporting the rotor shaft. The cylinder further contains a sleeve that is fastened to the casing and inside which is mounted the bearing, and at least one load sensor that is mounted on the sleeve while being offset axially relative to the bearing.
