Abstract: The present invention relates to an electromechanical actuator comprising a housing, an electric motor, a roller drive and a rotor rotation angle sensing unit received in said housing. The rotor of the electromechanical actuator is mounted within the housing and configured to rotate in bearing supports. Openings for supplying and removing lubricant are arranged in the housing in the vicinity of the bearing supports, the opening allowing to replace lubricant without disassembling the actuator, thus simplifying maintenance and operation.
