Claim:
A bearing forming a member for transmitting an axial force, the bearing comprising: an inner ring, an outer ring, balls disposed in a raceway chamber formed between the inner and outer rings, and an annular shield mounted on a radially inner edge face of a first ring selected from the inner and outer rings, a second ring being the one of the inner and outer rings not selected as the first ring, and wherein the inner and outer rings are mounted with freedom to pivot angularly about a point common to the axes of symmetry of the two rings, wherein the inner and outer rings are mounted such that the inner and outer rings can pivot angularly independently from one another and can pivot with respect to one another, and the shield extends from the first ring to the vicinity of a portion of the second ring that is centered on the point, the shield has an end portion with a surface disposed facing said portion, and wherein said surface co-operates with said portion to form a gap of constant width during angular pivoting of the inner and outer rings relative to each other.
