A bearing assembly, including: a housing having a through hole; first and second bearings coaxially set in the through hole, the first bearing is located at one end and the second bearing is located at an other end of the through hole, and both the first and second bearings include inner and outer rings. A first shaft sleeve is set between the first and the second bearing along an axial direction. An end cap located at the other end of the through hole, is connected with the housing and adapted to rotate relatively to the housing. The first bearing is located between the end cap and the first shaft sleeve along the axial direction. Accordingly, the end cap can be connected with the housing for preventing the end cap from falling out of the housing, thus the bearing assembly is configured into an integrated piece for transportation and usage.
