Abstract
A bearing assembly includes an outer ring having an outer raceway and an inner ring having an inner raceway and a flange defining an outer diameter of the inner ring. A plurality of rolling elements is retained between the outer and inner rings on the outer and inner raceways. A cage has first and second side rings interconnected by a plurality of bridges to form a plurality of windows, each window receiving a respective rolling element to maintain relative spacing between adjacent rolling elements. At least some of the bridges include a projection on a radially inner side such that the plurality of proj ections together define an inner diameter of the cage, the inner diameter of the cage being smaller than the outer diameter of the inner ring to create interference and deformation of the cage as the cage is installed over the flange of the inner ring.
