Abstract
A thrust bearing assembly for retaining a ball screw of an actuator in a housing and driving a position sensor in a control system. The thrust bearing assembly has a cylindrical body with an annular radial projection having parallel first and second inner outer race surfaces. Gear teeth are located on the peripheral surface of the radial projection. First and second roller bearing and associated first and second outer races are located on said cylindrical body. A locating plate attached the housing urges the second outer race toward the housing to bring the second roller bearing into engagement with the second inner race and the first inner race into engagement with the first roller bearing and first outer race to fix the position of the ball screw in the housing. The ball screw is connected to receive rotary torque from a drive gear to position a translating ball nut within the housing. Rotation of the ball screw correspondingly rotates the cylindrical body such that the gear teeth on the peripheral surface provides a sensor with a signal indicative of the location of the ball nut within the housing.
