32 connected to the cage 25 in a position offset relative to its radial plane of symmetry as before the connecting studs are broken during the assembly of the bearing with two rows of angular contact balls in the alternative form illustrated in fig9 once again there is a bearing with two rows of angular contact balls which is similar to that illustrated in fig1 identical components bear the same reference numerals here once more are in particular the outer ring in one piece 1 and the two independent inner rings 2 3 having the same outer grooves 2a 3a the difference in this alternative form is that a retention piece of different structure which can be seen laid out in fig1 and which is designated as a whole by 33 is used the retention piece 33 has a connector element 14 identical to the preceding one and a part forming a cage 34 provided with a single lateral row of pockets 35 interacting with one of the rows of balls 4 the connection between the element 14 equipped with its hooks 15 and 16 and the cage 34 is made as before by means of three connecting studs 18 as before the portion 20 of the studs 18 which is integral with the element 14 is in the radial plane of symmetry of the connector element 14 the position of the parts 21 on the bore of the cage 14 is offset relative to the radial axis of symmetry of the bearing as a whole after assembly as can be seen particularly in fig9 thus as before causing the weakened connection to break during the assembly of the.
