An autothrottle system for an aircraft includes a motor, an actuator assembly, and a position sensor connected to a moving portion of the actuator assembly. An electronic controller is provided for receiving an aircraft engine operating parameter and to control the motor to rotate the shaft to adjust the engine operating parameter based on the engine operating parameter and a position signal received from the position sensor. The actuator assembly has a bearing assembly having a plurality of bearings configured to contact a surface of the shaft to effect movement of the throttle lever attachment end.
