[0023] Specifically, the cross section of the limiting block 32 is circular, and can cooperate with the stop block 34 to limit the inner ring of the bearing.

[0024] In this embodiment: a blocking rod 33 is fixedly connected to the lower surface of the limit block 32. When performing a bearing test, the inner ring of the bearing is placed on the block 34, and then the telescopic cylinder 35 is controlled to push the block 34, which then pushes the bearing upward.
