Claim 0:
1. A cage for a bearing, the bearing including an inner ring, an outer ring and a plurality of rolling elements, the bearing cage comprising:
an annular body disposeable between the inner ring and the outer ring and having a centerline, first and second axial ends spaced apart along the centerline, an inner circumferential surface, an outer circumferential surface and a plurality of pockets extending radially between the inner circumferential surface and the outer circumferential surface and spaced circumferentially about the centerline, each pocket being configured to retain a separate one of the plurality of rolling elements, and a plurality of channels extending axially through the annular body and spaced circumferentially about the centerline, each channel having a first section extending from the first axial end of the annular body and connected to a separate one of the plurality of pockets and a second section extending from the connected pocket to the second axial end of the annular body, the first section of each channel circumferentially overlapping at least a portion of one pocket adjacent to the connected pocket and the second section of each channel circumferentially overlapping at least a portion of another pocket adjacent to the connected pocket and each channel being configured such that liquid entering one of the first and second sections of the channel traverses the one channel section, passes around a rolling element disposed within the one pocket fluidly connected with the one channel section, enters the other one of the first and second sections of the channel and exits the cage out of the other channel section.
