A bearing housing for an exhaust gas turbocharger may include a bearing housing cover arranged on a bearing housing wall. The bearing housing cover may include a penetrating rotation-symmetrical sealing recess with a centre axis and may have a locating surface facing the bearing housing wall and radially extending from the centre axis. The bearing housing may include a sealing bush arranged in at least one region of the sealing recess. The sealing bush may have a stop surface arranged opposite the locating surface and may include a penetrating shaft recess disposed rotation-symmetrical relative to the centre axis. The bearing housing cover may further include an at least partly circulating groove disposed on the locating surface radially spaced from the centre axis. The groove may include a drainage region arranged below the centre axis and extending from the centre axis radially to an outside.
