Abstract: A rolling element bearing includes a plurality of rolling elements, a bearing inner ring and a bearing outer ring. The rolling elements are arranged circumferentially around an axis, and radially between the inner ring and the outer ring. The inner ring includes a plurality of first passages, a second passage and a channel that extends axially into the inner ring. The first passages are arranged circumferentially around the axis. The first passages respectively extend axially through the inner ring from a plurality of first passage inlets to the channel. The second passage includes a second passage inlet that is substantially axially aligned with one of the first passage inlets. The second passage extends radially through the inner ring to a second passage outlet.
