Abstract
An inner ring for a bearing assembly with an inner surface having a plurality of circumferentially spaced axial slots defined therein each having a flat axially extending bottom wall and a plurality of circumferentially spaced partial circumferential slots defined therein each intersecting one of the axial slots and extending circumferentially therefrom around a respective portion of a circumference of the inner surface, shoulder radial holes extending therethrough each from a respective one of the circumferential slots to a corresponding one of the shoulders, and race radial holes extending therethrough each from a respective one of the circumferential slots to a corresponding corner of the inner race. The radial holes are circumferentially offset from the axial slots. A bearing assembly and a method of lubricating such an assembly are also discussed.
