A split inner ring of a bearing assembly comprises first and second rings, a plurality of holes, a circumferential annulus and a lubrication system. The first and second rings are configured to mate axially at inside side surfaces to define an inner raceway formed on an outer surface of the rings. The plurality of holes are circumferentially spaced and extend from an outside side surface to an inside side surface of the first ring. The circumferential annulus is formed on the inside side surface of the first ring, between the inner raceway and an inner surface of the first ring, and intersects the plurality of holes. The lubrication system connects the circumferential annulus to the outer surface of the first ring and the second ring. The lubrication system comprises circumferentially spaced slots in the first ring, or axial holes fluidly coupled with radial holes in the second ring.
