Abstract
The ball bearing (1) forms a member for transmitting an axial force and comprises an inner ring (3), an outer ring (4), balls (6) disposed in a raceway chamber (5) formed between the inner ring and the outer ring, and an annular shield (8) mounted on a radially inner edge face (32) of a first ring (3). The inner and outer rings (3, 4) are mounted with freedom to pivot mutually about a point (C1) common to the axes of symmetry (X3, X4) of the two rings. The shield (8) extends from the first ring (3, 4) to the vicinity of a portion (43) of the second ring (4) that is centered on said common geometric point (C1), and the shield (8) has an end portion (83) with a surface (831) that is a truncated sphere centered on the common geometric point (C1) or a truncated cone centered on the axis of symmetry (X3) of the first ring (3). This surface (831) is placed facing the centered portion (43) of the second ring (4) and co-operates therewith to form a gap (100) of a width (e100) that is constant during angular pivoting of the inner and outer rings (3, 4) relative to each other.
