1. A bearing assembly comprising: an outer ring having an outer surface and an inner surface, and an outer raceway formed on the inner surface; a split inner ring having a first ring and a second ring which mate axially to define an inner raceway formed on an outer surface of the first ring and the second ring, and an inner surface; bearing elements disposed between the outer raceway and the inner raceway, and adapted to rotatably move between the split inner ring and the outer ring about a central axis of the bearing assembly; a plurality of circumferentially spaced holes, each hole extending from an outside side surface of the first ring to an inside side surface of the first ring, the inside side surface of the first ring mating against an inside side surface of the second ring; a first circumferential annulus formed on the inside side surface of the first ring or the inside side surface of the second ring between the inner raceway and the inner surface, the first circumferential annulus fluidly linked to the plurality of circumferentially spaced holes; and a lubrication system connecting the first circumferential annulus to the outer surface of the first ring and the second ring.
