Whether the material is properly selected is still a factor that must be considered in INA bearing failure analysis. The main task of bearing failure analysis is to find out the main factors causing the failure of stainless steel bearings based on a large amount of background materials, analysis data and failure forms, in order to target improvement measures to extend the service life of the bearings and avoid sudden early failure of the bearings. Mounting conditions is one of the primary factors in the use of factors, bearing often due to improper installation and lead to changes in the force state between the parts of the whole set of bearings, bearings in abnormal conditions of operation and early failure. According to the technical requirements of bearing installation, use, maintenance and repair, the load, speed, working temperature, vibration, noise and lubrication conditions of the running bearing are monitored and inspected, and abnormalities are found to immediately find the cause and make adjustments to restore it to normal.

1. whether the outer packaging is clear: in general, the brand has its own special design staff to design the outer packaging, and arrange for the production conditions of the factory to produce production, so the packaging from the lines to the color block are very clear, unambiguous.

2.whether the steel print word is clear: INA bearing body will be printed on the brand words, markings, etc.. The font is very small, but most of the factory production using steel printing technology, and before the heat treatment on the pressure of the word, so the font is small, but concave deep, very clear. And counterfeit products, the font is not only blurred, due to the printing technology is rough, the font floating on the surface, some even easily erased by hand.

3. whether there is noise: left hand holding the stainless steel bearing body set, the right hand plucking the jacket to make it rotate, listen to its whether there is noise. As most of the counterfeit products production conditions are backward, completely manual workshop operation, in the production process will inevitably be mixed with sand impurities, hidden in the INA bearing body, so in the rotation will make a noise. This is the biggest difference with the strict implementation of production standards, and with the machine operation of the brand between the genuine factory.

4. whether the surface has cloudy oil stains: this should pay special attention when buying stainless steel bearings. As the current domestic anti-rust technology is not particularly home, so the INA bearing body anti-rust treatment is easy to leave a thick oil stains, hold in the hands of sticky, thick, and foreign original bearings almost invisible traces of anti-rust oil, but particularly careful connoisseurs said the bearing smells a taste, is certainly under the anti-rust oil, just can not see it.

5. chamfering is uniform: the so-called bearing chamfering, that is, the intersection of the horizontal and vertical, counterfeit bearings due to the limitations of production technology, in these edges and corners of the parts are not handled satisfactorily.

The metallurgical quality of INA bearing material used to be the main factor affecting the early failure of rolling bearings. With the metallurgical technology (such as bearing steel vacuum degassing, etc.) progress, raw material quality has been improved. Raw material quality factors in the analysis of stainless steel bearing failure has significantly decreased, bearing but it is still one of the main factors affecting bearing failure.
