PURPOSE: A device for testing the durability of a bearing is provided to simultaneously test the durability of a plurality of target bearings and to prevent the damage and the deformation of a testing device by applying an axial load to only the target bearings. CONSTITUTION: A device(100) for testing the durability of a bearing comprises a rotary shaft(110), a first member(131), and a second member(133). The rotary shaft is rotated by a driving member(120) and inserted into a pair of the target bearings. The first member is protruded inwards to a radial direction and includes a first projection portion supporting one of the pair of the target bearings to an axial direction. The second member is protruded inwards to the radial direction and includes a second projection portion supporting the other target bearings to the axial direction. The first and second members are mutually connected by one or more cylinders. An axial load is actuated on the pair of the target bearings by the operation of one or more cylinders. |
