Abstract: A bearing assembly and a rotary shaft apparatus employing the same are provided. The bearing assembly is rotatably coupled with a first shaft and a second shaft. The first bearing housing includes a first annular recess having a first axial depth. The first bearing is connected with the first annular recess and the first shaft and has a first axial thickness. The second bearing housing includes a second annular recess having a second axial depth. The second bearing is connected with the first annular recess, the second annular recess and the second shaft and has a second axial thickness. The spacer is disposed between the first bearing and the second bearing and has a third axial thickness. The sum of the first axial thickness, the second axial thickness and the third axial thickness is greater than the sum of the first axial depth and the second axial depth.
