The bearing arrangement includes a one-piece gas bearing sleeve (32) configured to rotatably support the drive shaft (4) and made in molybdenum or in a molybdenum alloy, the one-piece gas bearing sleeve (32) including a radial bearing surface (33) configured to Surround the drive shaft (4).

There is disclosed a bearing housing for a turbocharger. The bearing housing comprises a body and a mounting flange. The body is configured to receive one or more bearings. The one or more bearings are configured to support rotation of a shaft about an axis. The mounting flange extends around the body. The mounting flange comprises a plurality of bores, a first face and a plurality of cavities. The plurality of bores configured to receive a fastener therethrough. The first face is configured to engage a corresponding mounting flange of a turbine housing. The plurality of cavities are in communication with the plurality of bores. The plurality of cavities are axially recessed relative to the first face.

A roller for deflecting or guiding a metal strip to be coated in a metal melt bath may include bearing journals disposed coaxially with one another for rotationally supporting the roller. To obtain a high coating quality while hot-dip coating the metal strip, in particular steel strip, and to increase the service life of such a roller, each bearing journal may comprise a plurality of axially spaced annular elevations that have or are formed from a plain-bearing coating. The roller may comprise a steel roller shell, and each bearing journal may include a substantially cylindrical or circular-disk-shaped connecting steel portion that extends radially in the direction of the roller shell. At least one of the connecting portions may comprise a passage opening at an end face of the roller shell. The passage may be closed by means of a gas-permeable plug element comprised of ceramic material.”

A bearing bushing for a track has an annular shape including an inner peripheral surface, an outer peripheral surface, a first end face, and a second end face located axially opposite the first end face. The bearing bushing for a track includes an inner peripheral surface-side hardened layer formed to include the inner peripheral surface, an outer peripheral surface-side hardened layer formed to include the outer peripheral surface, a first end face-side hardened layer formed to include the first end face and having a region with a hardness of 63 HRC or more that has a thickness of 3 mm or more from the first end face, and an unhardened region lower in hardness than the inner peripheral surface-side hardened layer, the outer peripheral surface-side hardened layer, and the first end face-side hardened layer, and including at least the second end face. The bearing bushing is made of steel.

A rolling bearing has an outer diameter surface of the outer ring which is a fitting surface with a housing and the inner diameter surface of the inner ring, which is a fitting surface with a shaft. The outer diameter surface of the outer ring or the inner diameter surface of the inner ring is coated with a bonded film containing an organic binder, a solid lubricant powder such as molybdenum disulfide powder, and a friction/wear modifier such as antimony oxide powder. According to the rolling bearing, a creep resistance is kept excellent without causing increase in cost and size and being deformed and softened.
