Abstract
This ball bearing (1) forms an axial force transmission member and comprises an inner ring (3) and an outer ring (4), and a single series of balls (6) placed in a rolling chamber between the inner ring (3) and the outer ring (4). A first ring (4), amongst the inner ring (3) and the outer ring (4), forms a travel track (411) in a section of a sphere centered on a geometric point (C4) belonging to an axis of symmetry (X4) of this first ring (4). The first ring (4) supports a seal (11) insulating the rolling chamber relative to the outside. The second ring (3), amongst the inner ring (3) and the outer ring (4), is provided with a sealing zone (314) designed to interact with the seal and in the shape of a section of a sphere centered on a second geometric point (C3) belonging to an axis of symmetry (X3) of the second ring. The radii (R3, R4) of the sections of a sphere are different. In the installed configuration of the bearing, the first geometric point (C4) and second geometric point (C3) are superimposed and offset axially, along the axis of symmetry (X3) of the second ring (3), relative to the series of balls.
