The present invention relates to a bearing assembly 10 for a charging apparatus 500. The bearing assembly 10 comprises a bearing housing 400 and a shaft 530. The bearing assembly 10 further comprises a compressor-side bearing bushing 100 and a turbine-side bearing bushing 200 which together support the shaft 530 inside a bearing bore 410 of the bearing housing 400. The bearing assembly 10 is configured to supply unequal amounts of lubricant to a compressor-side outer lubrication gap 115 of the compressor-side bearing bushing 100 and to a turbine-side outer lubrication gap 215 of the turbine-side bearing bushing 200. The bearing assembly 10 is further configured to supply unequal amounts of lubricant to a compressor-side inner lubrication gap 113 of the compressor-side bearing bushing 100 and to a turbine-side inner lubrication gap 213 of the turbine-side bearing bushing 200.
