Abstract
A radial rolling element bearing (10) for supporting a shaft (14) for rotation with respect to an adjacent support surface (38). The radial rolling element bearing (14) includes a plurality of rolling elements (18) and a race (22). The race includes a convex first surface (44) that forms a raceway for the plurality of rolling elements and a second surface (48) opposite the convex first surface having a profile that forms a hollow space (52) between the second surface of the race and one of the adjacent support surface and the shaft. The hollow space has a first volume when a first radial load is applied to the bearing, and the hollow space has a second volume less than the first volume when a second radial load greater than the first radial load is applied to the bearing.
