Beschreibung
Zusammenfassung:	The invention relates to a turbocharger with a variable turbine geometry, comprising a turbine (1, 2, 5, 6, 7, 8, 9) with a turbine rotor (1) which is rotatably mounted in a turbine housing (2); the turbine (1, 2, 5, 6, 7, 8, 9) comprising a blade bearing ring (5) being arranged about a turbine axis (A); wherein the blade bearing ring (5) supports a number of blade shafts (6); wherein adjustable guide blades (7) are arranged at the blade shafts (6) on a front side of the blade bearing ring (5); wherein blade levers (8) are arranged at the blade shafts (6) on a rear side of the blade bearing ring (5); wherein an adjustment ring (9) is arranged coaxially with the blade bearing ring (5) and engages with the blade levers (8), a rotation of the adjustment ring (9) relative to the blade bearing ring (5) providing for an adjustment of the guide blades (7); wherein the adjustment ring (9) comprises at least one axially protruding bearing stop (10), the bearing stop (10) being provided by deformation of the adjustment ring (5).
