The rolling bearing device comprises an outer ring (11), an inner ring (10) comprising a bore (10a) for mounting the device on a shaft, and at least one row of rolling elements (14) positioned between the rings. The bore (10a) comprises weakening means (23) that locally reduce the mechanical strength of the inner ring in respect of radial stressing. The weakening means (23) between them delimit contact surfaces where the bore (10a) makes contact with the shaft, running at least in the circumferential direction. The outer ring (11) comprises a casing, two attached raceways (12, 13) positioned in the casing, and an elastic ring (16) pressing against the casing and one of the raceways (12).
