The invention relates to a bearing test device. The bearing testing device comprises a sealed housing having a cavity; a rotating shaft for mounting a test bearing is disposed in the cavity; the rotating shaft is connected with a driving motor; the outer side of the rotating shaft is provided with a radial loading shaft sleeve extending along the axial direction of the rotating shaft; and the bearing test device further comprises a radial load loading mechanism which applies a radial load to the test bearing through the radial loading shaft sleeve from the radial direction of the rotating shaft. According to the bearing test device of the invention, the outer side of the rotating shaft is provided with the radial loading shaft sleeve; the radial load loading mechanism applies the load to the loading shaft sleeve, and the radial loading shaft sleeve transfers the load to the test bearing; and therefore, the radial load loading mechanism will not directly apply a load to the rotating shaft, damage to the rotati
