Abstract
A bearing includes an inner ring having an outer surface and a cage having both an inner surface and an outer surface. The cage inner surface is positioned to be in opposition to the inner ring outer surface. The bearing further includes an outer ring having both an inner surface and an outer surface. The outer ring inner surface is positioned to be in opposition to the cage outer surface. One or more of the inner ring outer surface, the cage inner surface, the cage outer surface, and the outer ring inner surface defines a non-circular circumferential profile.
