Abstract
A bearing cage for a bearing assembly is disclosed herein. The bearing cage includes a first ring, a second ring, and a plurality of crossbars extending between the first ring and the second ring to define a plurality of rolling element pockets. A first terminal end of each of the plurality of crossbars is connected to the first ring and a second terminal end of each of the plurality of crossbars is connected to the second ring. A medial portion of each of the plurality of crossbars is defined between the first terminal end and the second terminal end, and a pair of recesses are defined on opposing circumferential sides of the medial portion.
