What are the possible problems with the appearance of the bearing? (2)

1. Peeling and folding
The one-sidedness of these two shortcomings is not firmly fused with the base metal, and there are often different levels of decarburization or carbon-lean phenomena around them. The raw materials are simply collapsed, dented or worn, which is very detrimental to the life and accuracy of the bearing.
4. Maintain the riveting or welding quality of the frame
Pay attention to whether the rivet head is offset, inclined, slack, lack of flesh or "double eyelids", whether the welding position is accurate, whether the welding point is too large or too small, whether the welding is not strong or the welding is too large to form a stuck rolling body Phenomenon, whether the quality of the pressure slope, edge closing, caulking and gouging of some cages is guaranteed, whether the rolling body can not fall out of the cage and can rotate freely, these points such as different requirements, small ones will cause bearing noise and If the rotation accuracy is reduced, the maintenance frame may fall apart and cause mechanical obstacles or incidents.
