How to check the appearance of INA bearings

When using the INA bearings, we should first check the appearance of the bearings, to judge the Is it right? Meet our required standard. And share a piece to share we should examine those parts.
INA bearing inspection should be carried out in the spotlight, careful observation of the appearance of cracks and other parts, bearing.
1, a variety of mechanical injuries, such as abrasion, scratch, bruise, bumps and so on, will cause the bearing mounting bad, causing partial load and stress concentration, decrease the rotating precision and service life.
2, 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.
3, all kinds of cracks, cracks such as raw materials, heat treatment, forging crack crack and grinding cracks, these cracks in the bearing in operation, will become the source of stress concentration and rapid expansion, resulting in bearing rupture, has 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.
4, peeling and folding, these two kinds of defects of the local and the base metal binding is not strong, but often to varying degrees around the existence of decarbonization phenomena of poverty or carbon, the material easy to fall, dent or wear, very adverse to the bearing life and accuracy.
5, the holder of the riveting or welding quality, observe whether the main rivet head deviation, 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 excessive rolling body caused by welding stuck phenomenon.
The above is our check in INA bearing in the focus of the inspection part, in addition to 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.
INA bearing inspection should be carried out in the spotlight, careful observation of the appearance of cracks and other parts, bearing.
1, from the skin and fold:
These two kinds of defects of the local and the base metal binding is not strong, but often to varying degrees around the existence of decarbonization phenomena of poverty or carbon, the material easy to fall, dent or wear, very adverse to the bearing life and accuracy.
2, the holder of the riveting or welding quality:
The main observation of the rivet head whether deviation, 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 excessive rolling body caused by welding stuck phenomenon. The above is our check in INA bearing in the focus of the inspection part, in addition to 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 abrasion, scratch, bruise, bumps and so on, will cause the bearing mounting bad, causing partial load and stress concentration, decrease the rotating precision and service life.
5, all kinds of cracks:
Cracks such as raw materials, heat treatment, forging crack crack and grinding cracks, these cracks in the bearing in operation, will become the source of stress concentration and rapid expansion, resulting in bearing rupture, has 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.
