Abstract
A tandem rolling bearing including a first rolling element subassembly and a second rolling element subassembly is provided. The subassemblies both include a plurality of rolling elements and a cage. The cages each include a ring and a plurality of axial projections having axial free ends. The free ends of the cages in the first and second subassemblies face each other. Rolling element retaining pockets are defined between adjacent pairs of projections in the cages. The projections include pairs of lugs that, together with a partially spherical retaining surface provided between the projections of each of the pockets, contact and retain the rolling elements in the pockets.
