A bearing device for a turbocharger according to one embodiment of the present invention includes: a rotational shaft; a journal bearing device including a compressor-side journal bearing and a turbine-side journal bearing; a bearing housing including a compressor-side bearing supporting portion, a turbine-side bearing supporting portion, and a bearing housing main body; and a lubricant oil guide member extending along a circumference direction of the rotational shaft, at an outer circumference side of at least one of the compressor-side bearing supporting portion and the turbine-side bearing supporting portion. When a virtual line extending vertically downward from a rotational center CL of the rotational shaft is defined as a reference line VL in a state where an oil discharge port is orientated downward, the lubricant oil guide member extends from the reference line VL along the circumference direction toward each of one side and another side of the reference line VL over a predetermined angle θ about the rotational center CL of the rotational shaft.

A plain bearing arrangement for a shaft loaded with a circumferential radial force, having a bearing ring arranged in a rotationally fixed manner in a housing component and having a first running surface formed on the inner circumference, and a second running surface formed on the outer circumference of the shaft or on the outer circumference of a sleeve arranged on the shaft, the second running surface being mounted in a sliding manner on the first running surface, wherein a device for axially feeding a lubricant to an end side of the shaft is provided, and at least one axially extending, radially open groove that is axially open in a direction of the end side of the shaft is formed in the second running surface.

The provided is a bearing device for a crankshaft of an internal combustion engine including: a crankshaft having a plurality of journal portions; main bearings for supporting the crankshaft; and a bearing housing, wherein a range in which the oil groove of the upper-side halved bearing of the second main bearing is formed in the circumferential direction includes at least a range of a circumferential angle of 20° within the ±45° region, a circumferential end portion of the oil groove on a rotationally forward side communicates with the crush relief at a minimum, and is open to a circumferential end face at a maximum, and a circumferential end portion of the oil groove on the rotationally backward side of the journal portion is positioned on a circumferential center portion side of the upper-side halved bearing from a circumferential end face of the upper-side halved bearing.

An assembly having an outer component, an inner component, and a ring positioned between the outer component and the inner component, where the ring has at least one radially extending projection adapted to seat within at least one groove in the inner component or outer component, and where the projection is adapted to compress radially to allow rotational or axial movement between the inner component and the outer component upon application of rotational or axial force respectively to at least one of the inner component or the outer component.
