A wheel hub assembly for mounting on an upright of a vehicle has a flanged outer ring provided with a tubular mounting portion inserted over a first axial length (L1) inside a seat of the upright; and a plastic cover having a mounting portion which is also engaged inside the tubular portion, wherein the mounting portion extends outside the tubular portion over a second axial length (L2) which, together with the first axial length (L1), covers less than a mounting length (L) inside the seat.

An impeller-type liquid ring compressor having a particular bearing configuration. Such a bearing arrangement may completely support the impeller as it rotates, eliminating many of the problems inherent in the prior art designs without changing the general overhung impeller design. This may allow the impeller-type liquid ring compressor to be easily retrofitted in existing use environments, such as, for example, oil and gas processing facilities, oil refineries, and petrochemical processing facilities. In some exemplary embodiments, a thrust bearing may be located on the front face of the impeller, or radial bearings may be disposed between the vanes of the impeller. A radial bearing and thrust bearing may further be disposed on the shaft side of the impeller close to the impeller itself. The compressor may be configured so that the process fluid carries heat away from each of these bearings.

A crankshaft bearing support structure includes a cylinder block having a first holding portion; a first plain bearing held by the first holding portion of the cylinder block; a crank cap fastened to the cylinder block, the crank cap having a second holding portion; a second plain bearing held by the second holding portion of the crank cap; and a crankshaft having an axis of rotation, the crankshaft being rotatably held by the first plain bearing and the second plain bearing and configured to receive an explosive load from a piston via a connecting rod. The crankshaft flexes, when subjected to the explosive load, in a direction of the explosive load. The crank cap in provided with a mechanism which causes the second holding portion to flex in a manner that a bearing holding surface of the second holding portion follows flexure of the crankshaft subjected to the explosive load.

A bearing for mounting an anti-roll bar on a bogie frame, the anti-roll bar extending along an axis transverse to the bogie and being mobile in rotation relatively to the frame around the axis, the bearing including a first half-shell, and a second half-shell adapted so as to be attached on the first half-shell by means of a first attachment system, the first half-shell and the second half-shell then forming a housing crossing through along the axis and adapted for receiving the anti-roll bar. The first half-shell is distinct from the frame and adapted so as to be attached on the frame by means of a second attachment system.

A bearing assembly installed within a turbocharger housing between a turbine wheel and a compressor impeller mounted for rotation together on a turbocharger shaft may include a journal bearing disposed on a corresponding portion of the turbocharger shaft, a thrust bearing having a thrust bearing surface, and a bearing carrier. The bearing carrier may include a carrier body, a carrier body bore extending axially through the carrier body and receiving the journal bearing therein, and a thrust bearing seat on the exterior of the carrier body facing the turbine wheel. The thrust bearing seat may have a complimentary shape to the thrust bearing surface of the thrust bearing, the thrust bearing disposed between the carrier body and the turbine wheel and engaging the thrust bearing seat. The bearing assembly may further include an anti-thrust bearing surface facing the compressor impeller, and an anti-thrust bearing mounted to the anti-thrust bearing surface.
