In a bearing apparatus provided herein a hard steel shaft is an opposite shaft of an Al-Sn-Si based alloy plain bearing. Its wear resistance is enhanced. The bearing apparatus comprises a steel shaft having hardness of Hv 500 or more at least on a surface thereof, and a plain bearing. The plain bearing is formed of an aluminum alloy containing 2 to 10 mass% of Si, 8 to 18 mass% Sn, and the balance being Al and unavoidable impurities, wherein the volume of Sn phase is 50% or more of the volume of the Si particles( the average particle diameter of Si of the aluminum alloy is 4 to 10 µm). The aluminum alloy has a hardness of Hv 45 or more.

A bearing comprises a resin matrix filled with fluoropolymer, graphite, and other discrete particles of an additive material that is attached to a backing material. The specific selection and mix of fillers with the resin matrix provides the desired blend of bearing properties such as wear resistance, fatigue and erosion resistance and low friction whilst maintaining sufficient flexibility for being formed into flanged cylindrical geometries without detriment to the adherence of the lining to the backing. A method for manufacturing a bearing comprises depositing to a backing material a fluid polymer bearing material comprised of a resin matrix filled with fluoropolymer, various fillers, and discrete particles of an additive to form a continuous consolidated bearing material, and curing the lining material to bond the lining material onto the backing material.

The invention relates to a bearing arrangement for a shaft (3) of a turbine wheel (2) or of a turbine wheel (2) and of a compressor wheel (4), wherein - the turbine wheel (2) is driven by the exhaust gas of a vehicle drive unit, said bearing arrangement comprising - a static housing (9), which - together with a bearing bushing (10) arranged in a rotationally movable manner relative to the housing (9) - encloses a first bearing gap (11), wherein - the bearing bushing (10) accommodates the shaft (3) in a rotationally movable manner and encloses a second bearing gap (12) together with the shaft. The invention is characterized in that a ratio (R1/R2) of radii (R1, R2) of the first bearing gap (11) and of the second bearing gap (12) with respect to a rotational axis (14) of the shaft (3) changes at least once over the maximum axial extent (x) of the bearing bushing (10).

A connecting rod (100) and method for making the same are disclosed. A connecting rod may include a shaft extending between a piston pin end (102) and a crankshaft pin end (104). The piston pin end generally defines a bore opening (106) extending along an axis. The connecting rod further includes a bore surface (110) formed integrally with the piston pin end and extending about an inner circumference of the bore opening. The bore surface may define a plurality of dimples (112) that extend axially along the bore surface. The bore opening may further include profiled surfaces (122a, b) adjacent opposing ends of the piston pin bore opening.
