Method of forming sheet metal bearing cage with inner and outer retention and roller-cage assembly for a bearing

A method of forming a cage for rolling elements of a radial roller bearing, the method comprising:

• forming a cage ring with a first axial flange and a second axial flange spaced from the first flange, and cage bars extending between the first axial flange and the second axial flange that form a plurality of roller pockets, the cage bars, together with the first axial flange and the second axial flange forming a U-shape in cross-section;
• and
• forming retention scallops that extend axially inwardly in each of the first and second axial flanges, the retention scallops being generally centered about the cage bars, the cage bars being located radially inwardly of a pitch circle of the rolling elements, and the retention scallops extending axially inwardly at a position radially outwardly from a pitch circle of the rolling elements to a position where portions of each of the retention scallops axially overlap end portions of adjacent rolling elements.
