The outer ring ( 3 ) of a motor-vehicle wheel-hub bearing ( 1 ) is housed in a cylindrical seat ( 9 ) of a strut ( 10 ) and is locked axially, on one side of the strut ( 10 ), by means of a radially inwardly-projecting rim ( 18 ) formed by cold deformation of a tubular portion ( 17 ) of the seat ( 9 ) and, on the other side, by means of a shoulder ( 11 ). A resiliently compressible ring ( 19 ) is inserted into the seat ( 9 ) of the strut ( 10 ) so as to be compressed axially between a lateral surface ( 12, 13 ) of the outer ring ( 3 ) of the bearing and the shoulder ( 11 ) or the deformed rim ( 18 ) of the seat ( 9 ), respectively, to compensate for any relative thermal expansion between the bearing and the seat. |
