The supporting ring (22) is attached to a fillet (18) of the centre shaft (12) and rests against the inner race (40). The supporting ring (22) comprises an annular boss (23) protruding outside in the axial direction and resting against the inner race (40). The supporting ring (22) and the inner race (40) form a gap radially outside the boss (23) with the adhesive gasket (90) set in the gap. The adhesive gasket (90) is set between the supporting ring (22) and the inner race (40). The adhesive gasket (90) serves for the attachment of the supporting ring (22) to the inner race (40). Method for forced fitting of the bearing assembly and the supporting ring on a shaft is proposed as well. |
