Abstract
A bearing unit (1) for a turbocharger is provided having a bearing housing (5) extending in an axial direction and having a through-hole, and a rolling-contact bearing (3) arranged coaxially within the through-hole and having a bearing inner ring (7), a bearing outer ring (13) divided axially into first and second part rings (9, 11), and a number of rolling-contact elements (15). The bearing outer ring (13) is mounted in a vibration-damping oil film (23), and the two part rings (9, 11) are spaced axially apart from each other by a pretensioning spring (19). The first part ring (9) has a first groove (43) with a first securing ring (39) arranged therein, and the first securing ring (39) is supported axially from the outside against the bearing housing (5).
