Abstract
This bearing comprises an external piece (10) with a cylindrical housing (11), a hollow insert sleeve (20) with a circular external wall (21) and a curvilinear triangular internal wall (22), an internal piece (30) with a circular external seating (31) and rolling elements (40) interposed between sleeve and seating. The sleeve is a relatively thin and, for example, press-formed bush, with non-constant thickness, engaged under force in the housing in such a way that the external piece (10) alone exerts a prestress. Application to systems in which it is necessary to obtain a bearing effect without the slightest radial play without it being necessary to effect an adjustment, such as an automobile suspension with trailing arms for example.
