Abstract
A thrust bearing cage including an improved lubrication feature is disclosed. The thrust bearing cage includes a first rim and a second rim with a plurality of crossbars extending therebetween to define rolling element pockets. Each crossbar of the plurality of crossbars includes: a first radial flange extending from the first rim; a second radial flange extending from the second rim; and a medial radial flange connecting the first radial flange and the second radial flange. The medial radial flange is axially offset from the first radial flange and the second radial flange. At least one of the first radial flange, the medial radial flange, or the second radial flange includes a protrusion defining at least one ramped surface. The ramped surface creates a hydrodynamic effect, which guides the thrust bearing cage away from an adjacent surface, and ensures that a lubricated state is maintained.
