Abstract
Rollers (9a) having a frustoconical lateral wall interposed between two raceways (4, 6) of two rings (1, 2) alternate with rollers (9b) interposed between two other raceways (3, 7) of the rings (1, 2). A crown region (11) of the large base of each roller slides against the confronting raceway (7) or (6) on the outer ring (2). Crown regions (11) of the rollers (9a, 9b) of each series of rollers substantially pertain to a common ideal sphere (Sx,Sy) centered on a common apex (X, Y) toward which converges the lateral walls of the rollers of the same series and the associated raceways. The angle made between the two raceways of the outer ring is less than 90.degree.. By this arrangement is achieved, between the crown region of each roller and the raceway against which the crown region bears, a contact (T) distributed along a segment of a circle centered on the axis of the bearing.
