Abstract:
A pivot bearing cartridge for use in an actuator assembly, the bearing cartridge comprising:a shaft including first and second shaft raceways extending around a circumference of the shaft; a first outer sleeve extending around the circumference of the shaft including a first sleeve raceway generally aligned with the first shaft raceway and first and third lips; a second outer sleeve coupled to the first outer sleeve and extending around the circumference of the shaft, the second sleeve including a second sleeve raceway generally aligned with the second shaft raceway and second and fourth lips, wherein the first lip has a diameter that is less than a diameter of the second lip and the third lip has a diameter that is greater than a diameter of the fourth lip, whereby the first lip fits within the second lip and the fourth lip fits within the third lip, thereby coupling the first sleeve to the second sleeve and preventing rotation between the first and second sleeves; and first balls in the first shaft and first sleeve raceways and second balls in the second shaft and second sleeve raceways.
