摘要： Provided is a journal foil air bearing for supporting a load applied along a radial direction of a rotating shaft rotating about a centerline, the journal foil air bearing including a first top foil disposed to face an outer circumferential surface of the rotating shaft and surround the rotating shaft, a second top foil disposed to surround the first top foil, a bump foil provided as an elastically deformable member and disposed to surround the second top foil, a base foil disposed to surround the bump foil, and at least one separation preventer provided on the first top foil to restrain the first top foil from being separated along a longitudinal direction of the rotating shaft, wherein the separation preventer protrudes a preset length toward the second top foil and is restrained by the second top foil from moving in the longitudinal direction of the rotating shaft. According to the present invention, because the first top foil does not escape in the longitudinal direction of the rotating shaft during operation, the performance of the bearing may not be reduced and serious secondary damage due to the contact between the escaped first top foil and other components may not be caused.

摘要： A bearing assembly includes a roller bearing connected with a bearing support having a plate-shaped section. The bearing support has a receiving bore for an outer ring of the roller bearing, and the outer ring of the roller bearing is affixed to the bearing support with two affixing plates that are fixed to first and second end sides of the bearing support and that clamp the outer ring at two clamping surfaces. An axial spacing of the first and second end sides of the bearing support is smaller than an axial spacing of the clamping surfaces of the outer ring, and the two affixing plates have a different mechanical strength.
