Abstract
The ball-and-socket joint member includes an inner ring, of a general shape of revolution around a first axis, having an outer surface provided with an inner raceway, an outer ring, of a general shape of revolution around a second axis, having an inner surface provided with an outer raceway, and at least one row of balls aligned circumferentially, extending radially between the inner raceway and the outer raceway. The outer surface of the inner ring comprises a portion with a generally truncated sphere shape, forming the inner raceway. The inner surface of the outer ring comprises, for each row of balls, a groove of complementary shape to that of the balls of this row, said groove forming the outer raceway.
