摘要：
An electromechanical actuator (“EMA”) comprising an actuator drive unit (“ADU”) housing and a ball screw is disclosed. The ball screw and ADU housing may interface to form a multi-row thrust bearing (MRTB). Further, the ball screw may be situated at least partially about the ADU housing, an outer surface of the ADU housing may include a first ADU raceway, and an inner surface of the ball screw may include a second inner ball screw raceway. Either or both raceways may comprise hemispherical structures. Further, the first raceway and the second raceway may interface to form a multi-row thrust bearing
