A sliding bearing for a gearbox of a wind turbine, having a support body and a sliding layer which is applied on the support body, and on which a sliding surface is formed, wherein a lubricant distribution groove extending in an axial direction of the sliding surface is formed on the sliding surface. The support body is formed as a bush rolled from a support body strip, wherein a first longitudinal end and a second longitudinal end of the support body strip are connected to one another in a materially bonded manner, in particular by a welding connection, at a joint, wherein the joint is formed in the region of the lubricant distribution groove.

A bearing assembly comprising a first component and a second component, the first and second components being slidably disposed with respect to each other, wherein the first component slides relative to the second component in a first direction, wherein the first component comprises a plurality of first recesses formed in a first surface facing the second component, wherein the first recesses are distributed in a second direction perpendicular to the first direction with neighboring first recesses being spaced apart in the second direction with a first spacing, wherein the second component comprises a plurality of second recesses formed in a second surface facing the first surface of the first component, wherein the second recesses are distributed in the second direction with neighboring second recesses being spaced apart in the second direction with a second spacing, wherein the first recesses are sized to fit within the second spacings and the second recesses are sized to fit within the first spacings, and wherein the first and second components are urged into a relative position in the second direction in which the first and second recesses do not overlap one another.

Provided is a slide bearing capable of sustaining sliding performance over long period. A slide bearing has an upper case (2) configured to be attached to an upper support for attachment of a suspension to a vehicle body, a lower case (3) rotatably combined with the upper case (2) to form an annular space (7); and an annular center plate (4) and an annular sliding sheet (5) both placed within the annular space (7). The center plate (4) includes a bearing surface (40) slidable with the sliding sheet (5) and an annular groove (42) formed on the bearing surface (40) so as to hold lubricant. The annular groove (42) has an inner circumferential surface (43a) inclining down from the opening section toward the groove bottom section as it goes outwardly in the radial direction and an outer circumferential surface (43b) inclining down from the opening section toward the groove bottom section as it goes inwardly in the radial direction. A line P of intersection between the inner circumferential surface (43a) and the outer circumferential surface (43b) is located closer to the bearing surface (40) than to a back face (41) of the center plate (4).
