A shaft bearing assembly having a shaft supported in a bearing housing is described. The shaft bearing assembly includes a pressure reduction device for generating an underpressure inside the bearing housing. The pressure reduction device is operated by employing an incompressible fluid. Further, a method of reducing a pressure inside a bearing housing supporting a shaft is described. The method includes using an incompressible fluid for operating a pressure reduction device for generating an underpressure inside the bearing housing.
