Detailed by the appearance of imported bearings are examined

1, from the skin and fold:
These two kinds of defects of the local and the metal substrate binding is not strong, but often to varying degrees around the existence of carbon or carbon poor phenomenon, the material easy to fall, dent or wear, very detrimental to the bearing life and accuracy.
2, the holder of the riveting or welding quality:
The rivet head is offset, skew, relaxation, lack of meat or eyelid, welding position is correct, the solder joint is too large or too small, there is no welding is not strong or welding caused by excessive rolling phenomenon. The above is our check in the imported bearings in the inspection of key parts, except for the inspection of the part, such as the poor quality of the other type, such as illegible, damaged, defective should think seriously, may also not be accepted.
3, rust, black and ma:
The latter two are easy to store water and dirt of the defects, most likely to develop into rust. The cause of corrosion is the installation of non-performing, early wear and fatigue of the sources of pollution, a serious end-of-life bearings will rust.
4, a variety of mechanical injuries:
Such as scratch, scratch, bruise, bumps and so on, will cause the bearing mounting bad, causing partial load and stress concentration, decrease the rotation accuracy and service life.
5, the crack:
Cracks such as raw materials, heat treatment, forging crack crack and grinding cracks, these cracks in the bearing after the operation, will become a source of stress concentration and the rapidly expand, caused by bearing rupture, has a great influence on bearing life and work safety. In fact, for the important use of bearings, bearing factory is composed of parts of its 100% magnetic or radiographic inspection.

Imported bearing inspection should be carried out in light the lamp, careful observation of the bearing surface, cracks and other parts.1, from the skin and fold:
These two kinds of defects of the local and the metal substrate binding is not strong, but often to varying degrees around the existence of carbon or carbon poor phenomenon, the material easy to fall, dent or wear, very detrimental to the bearing life and accuracy.
