The present invention provides an improved thrust bearing for extreme service applications through the use of a novel bearing cage assembly and improved surface design of the external face of the circular inside sidewall of the bearing cage assembly and race components. The novel bearing cage assembly allows for an increase in the quantity and size of the roller elements contained within the bearing cage, compared to others known in the art, which substantially increases the thrust bearings' load capacity. Moreover, the employment of a smooth curved surface on the external face of the circular inside sidewall of the bearing cage assembly and race components effectively eliminates any sharp edges and corners which could otherwise damage the rotating shaft. Thus, the combination of these two features substantially increases the load capacity, wear and durability of the thrust bearing components.
