A bearing lubrication system includes a bearing assembly comprising a duplex bearing including an outer ring, an inner ring positioned radially inward from the outer ring, and two sets of circumferentially distributed rolling elements between the inner and outer rings. The bearing assembly further includes a housing radially surrounding the duplex bearing and including a lubricant flow passage in fluid communication with a source of lubricant. A flow orifice is located downstream of the lubricant flow passage for jetting the lubricant into the duplex bearing. The flow orifice has an axial location between the two sets of rolling elements.
