Abstract: A bearing unit (2), designed for attachment on a shaft of a pump assembly, has an inner sleeve (6) for receiving the shaft and a bearing sleeve (4) fixed on the outer periphery of the inner sleeve (6). At a first axial end (7) the inner sleeve (6) includes an engagement element (8), designed for positive, rotationally fixed engagement with the shaft or with a component (42) connected to the shaft. At a second opposite axial end the inner sleeve (6) includes a second contact shoulder (10), which fixes the bearing sleeve (4) in an axial direction (X). A pump assembly having such a bearing unit is also provided.
