A shaft component, which in particular can be connected or is connected to the input or output side of a gear box in a gas turbine engine, in particular an aircraft engine, wherein the shaft component has at least two regions comprising fiber reinforced plastic, with fibers in the at least two regions differing in their composition, their geometric properties, their density, their radial position, their axial position and/or in their fiber orientation in the shaft component.

Provided is a sliding bearing having an improved circularity and having achieved an increase in contact area with respect to a holder. The sliding bearing 1 comprises a pair of an upper halved member 2 and a lower halved member 3 which are portions of a cylinder halved in parallel to an axial direction. The sliding bearing has an oil hole 24 penetrating therethrough in a direction orthogonal to the axial direction of the cylinder. An inner peripheral portion 24a of the oil hole 24 has formed a laser-melted portion 25 which is an area in which a change in property in comparison to the original material has been caused by the thermal influence of laser.

A system for securing a bearing to a shaft includes a shaft having a raised portion extending radially outward from the shaft. The raised portion includes a first angled face on a first side of the raised portion and a second angled face on a second side of the raised portion. The bearing includes an outer race comprising a bearing surface on an inner face of the outer race, an inner race comprising a bearing surface on an outer face of the inner race and a third angled face on an inner face of the inner race that is configured to mate with the first angled face, and a plurality of rollers disposed between the inner and outer races.

A half thrust bearing for a crankshaft includes a back metal layer defining a first surface and a second surface, and a bearing alloy layer on the first surface to form a slide surface, and thrust relieves formed adjacent to both circumferential end surfaces and having a thrust relief surface consisting of the bearing alloy layer. Each circumferential end surface of the back metal layer includes an exposed end surface adjacent to the second surface, and a transition surface adjacent to the first surface. The bearing alloy layer further includes an extension portion covering the transition surface and having extension end surface adjacent to the exposed end surface, the extension end surface and the exposed end surface extending at least partly in the same plane.

A bearing cage assembly including two different cage halves formed from different materials is disclosed. The first cage half includes a first rim and a first plurality of arms extending from the first rim. The second cage half includes a second rim and a second plurality of arms extending from the second rim. The first cage half and the second cage half are fastened to each other via engagement between a plurality of first retainers of the first cage half with the plurality of second retainers of the second cage half.

Wheel hub assembly for motor vehicles, the group having a radially outer ring with at least one raceway, at least one radially inner ring with a related raceway and at least one ring of rolling bodies interposed between the radially outer ring and the radially inner ring, for sliding inside the raceways, at least one raceway being provided with superficial micropores having a depth (H) between 0.05 μm and 1.5 μm and defining respective micro-tanks for containing a lubricating grease.

The present invention provides an adjustable bearing assembly comprising a first bar and a second bar. The first bar comprises a first engagement surface which is configured to engage with a second engagement surface on the second bar. The first bar further comprises a bearing surface opposite the first engagement surface. One of the first or second engagement surfaces comprises a first plurality of teeth aligned in a first direction, wherein the plurality of teeth are configured to engage a plurality of inclined surfaces on the other of the first or second engagement surfaces such that a force applied to the second bar in the first direction causes the distance between the bearing surface and the second bar to vary.

A bearing including a bearing sidewall including a first circumferential end including an apex region, and a second circumferential end including a nadir region, where the first circumferential end and the second circumferential end are adapted to contact each other to form an interface, where at least one of the apex region or the nadir region includes a void to prevent contact between the apex region of the first circumferential end and the nadir region of the second circumferential end, where the bearing sidewall includes a substrate and a low friction material, and where at least one of the first circumferential end or the second circumferential end comprises an end face that is free of low friction material.

A spherical roller bearing providing an inner ring, an outer ring, rollers for rolling on raceways arranged on the rings, and a cage for holding the rollers spaced apart from each other. The cage having an annular core and a plurality of bars delimitating a plurality of pockets for the rollers, the annular core including two side faces from which the bars protrude axially outwardly, the inner and outer rings being rotatable with respect to each other around a bearing axis. The annular core further provides a plurality of spacing elements that protrude from the side faces of the annular core designed to come into contact with side faces of the rollers in order to prevent the rollers from moving axially towards the center of the bearing.
