An electromechanical rotary actuator (47) includes a housing (100) including first end (104) that extends to a second end (105) through an intermediate portion (107) that defines a longitudinal axis, and an internal cavity (108). An electric motor (114) is arranged within the internal cavity (108). The electric motor (114) includes a shaft (120) having first shaft end (122) and a second shaft end (123). A drive member (154) is arranged within the housing (100) along the longitudinal axis. The drive member (154) includes an input shaft (152) operatively coupled to the first shaft end (122) and an output shaft (155). An output shaft member (170) is coupled to the output shaft (155) of the drive member (154). At least one bearing assembly (138,184) supports one of the output shaft member (170) and the first shaft end (122), and a preload member (196) is arranged within the housing (100) and configured to apply a compressive axial force to the at least one bearing (138,184), the drive member (154) and the electric motor (114).
