Abstract
A bearing includes a first race in operational contact with a shaft, a second race in operational contact with the first race, and a third race in operational contact with the second race. The first, second and third races cooperate to define an aperture therethrough to the shaft. A connector is disposed through the aperture to functionally interlink the first race, the second race and the shaft to insure that the first race and the second race rotate substantially with the shaft. In operation, the first and second races define a first bearing surface that accommodates angular displacements of the shaft, and the second and third races define a second bearing surface that accommodates axial and rotational movements of the shaft.
