Abstract

A bearing unit rotatably supports a shaft of a pressure generating device, such a boost pressure generating device of an internal combustion engine. The bearing unit includes at least a first rolling-element bearing and a second rolling-element bearing, each rolling-element bearing having an inner ring and an outer ring. An annular space is defined between the respective inner and outer rings and rolling elements are disposed in the annular space. At least one volume element is disposed in the annular space and at least partially fills the annular space in an axial area.
