Abstract
A bearing bushing for a charging device may include an inner jacket surface including at least two radial depressions. A respective lowest point of the at least two radial depressions may be disposed on a circle having a radius R1. A plurality of plateau surfaces may be disposed circumferentially between the at least two radial depressions and may be offset radially towards an inside of the bearing bushing. The plateau surfaces may be curved and may have a constant radius R2. A ratio between the radius R1 and the radius R2 may correspond to the relationship: R1/R2=1.001 to 1.015.
