Abstract
A bearing assembly having an inner race ring () that defines an inner raceway and an outer race ring that defines an outer raceway on which the plurality of rolling elements () roll. The bearing raceways are machined using surface finishing operations to create preferred surface profiles and textures for improving lubrication performance. The profile of the raceway is initially created using a first grinding process to form a rough surface profile including a rough central band () and rough recessed side bands (). A second grinding process is used to smooth the central band. This raceway surface profile increases lubrication performance.
