A bearing for an exhaust gas turbocharger may include an annular body and a centrally arranged passage opening for bearing a shaft at least one of axially and radially with respect to a rotation axis. The body may include an oil pocket, a wedge surface extending at least partially in a circumferential direction, and a detent surface circumferentially spaced from the oil pocket via the wedge surface. The detent surface may include a predetermined wear height configured to be worn down over an operating lifespan of the bearing. A radially inner flange may extend at least partially along the wedge surface in the circumferential direction and define an inner sealing web. A radially outer flange may extend at least partially along the wedge surface in the circumferential direction and define an outer sealing web.

Axial bearing

A bearing for a turbocharger may include an annular body and a centrally arranged passage opening for bearing a shaft at least one of axially and radially with respect to a rotation axis. The body may include at least one segment extending at least partially about the passage opening in a circumferential direction. The at least one segment may include an oil pocket, a circumferentially extending wedge surface and a detent surface circumferentially spaced from the oil pocket. The segment may also include a radially inner flange extending at least partially along the wedge surface in the circumferential direction. The inner flange may define an inner sealing web that may continue uninterruptedly into the detent surface.
