A ball roller bearing (1) formed from a plurality of ball rollers (4) arranged between an outer bearing ring (2) and an inner bearing ring (3) and each of which comprises two parallel lateral surfaces (5, 6) and rolls, with their running surfaces (7) extending between said lateral surfaces (5, 6), in two groove-shaped raceways (10, 11) in an inner side (8) of the outer bearing ring (2) and the outer side (9) of the inner bearing ring (3), and which are held within individual cage pockets (12) of a bearing cage (13). The bearing cage (13) includes two interconnected lateral rings (15, 16) and two cage ribs which are connected thereto and in guiding contact with these lateral surfaces (5, 6) for axially guiding the ball rollers (4). The bearing cage (13) includes a cylindrical main part (17) having the lateral rings (15, 16) and pocket webs (14) and made of a cold-formable deep drawn steel, and the cage ribs are formed from two separate rib rings (18, 19) made of a thermally-treated carbon steel and are force and/or form-fittingly connected to the main part (17). |
