In order to achieve the interchangeability of bearings, the dimensional accuracy and shape and position accuracy of the outer diameter are required to be relatively high. Therefore, the outer diameter of the bearing needs to be polished.
[0003] According to a disclosed outer diameter grinding device for precision bearing manufacturing (publication number: CN215547273U), the above application can utilize the connecting spring and clamping block arranged on the rotating rod to fix the bearing.
