A bearing lubrication system having an exterior bearing cap circumscribing a motor shaft and having an annular recess with an axially extending depth, divided into first and second arcuate portions in the recess, forming lubrication inlet and outlet pockets in the recess, with the inlet and outlet pockets separated by axially extending walls, each wall having a height less than the depth of the recess for permitting grease to flow from the inlet pocket to the outlet pocket. The recess further has a sloped surface on an inner circumferential wall thereof to direct grease towards an adjacent antifriction bearing. A grease metering shield in the form of a solid or perforated annular plate adjacent the bearing directs grease to the contact region between the inner race and the rolling elements of the bearing.
