Abstract
A bearing cage assembly is disclosed herein that includes a first cage half formed as a plastic cage and a second cage half formed as a metal shell. The first cage half includes a first base rim and a first plurality of arms extending axially from the first base rim. The second cage half includes a second base rim and a second plurality of arms extending axially from the second base rim. The second plurality of arms are each formed by a first flange and a second flange. The first flange and the second flange are spaced apart from each other in a radial direction to define a receptacle dimensioned to receive a respective one of the first plurality of arms. Free ends of the first flange and the second flange are crimped over to retain the first cage half with the second cage half.
