A bearing assembly for a compressor of an internal combustion engine. The bearing assembly includes an outer ring having an outer cylindrical surface with a first and a second axial section. A positioning component which has a recess with an inner circumference is provided, wherein the positioning component surrounds the outer ring in a region of the second axial section and the positioning component and the outer ring are arranged displaceably relative to one another. To provide an alternative anti-rotation element and an alternative axial stop, at least one sub-section of an inner circumference of the recess of the positioning component is non-uniformly spaced from the center point and the cross-section of the second axial section around the circumference has at least one sub-section with a radius that varies around the contour of the outer cylindrical surface (radius variation). In a first circumferential section, the distance between the contour of the outer cylindrical surface of the second axial section and the axis of rotation is greater than the distance between the contour of the inner circumference of the recess of the positioning component and the axis of rotation in a second circumferential section.
