Abstract
A bearing cage assembly is disclosed that includes two sub-assemblies. Both cage sub-assemblies include a shell half formed from plastic, and defining a plurality of rolling element pockets and openings. Each sub-assembly also includes a frame half formed from metal, and including a rim and a plurality of crossbars. The shell halves are overmolded with the frame halves. The first cage sub-assembly and the second cage sub-assembly are connected to each other via insertion of the crossbars into the openings of the other sub-assembly, such that free ends of the crossbars engage the other rim.
