Appropriateness of the selection is still INA Bearing failure analysis must be considered. The main task of bearing failure analysis is based on a lot of background material, analysis of data and failure modes, find the cause of failure of the main factors bearing stainless steel in order to have targeted improvements to extend bearing service period, to avoid bearing the occurrence of sudden of early failure. Installation conditions are the primary factors that one of the factors bearing is often caused by improper installation package bearing force between the various parts of the state change, bearing in abnormal state of operation and early failure. According bearing installation, use, maintenance, maintenance of the technical requirements for operation of the bearings to bear the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, abnormal immediately find reasons to adjust to back to normal.

     1, the packaging is clear: Under normal circumstances, are factory brand has its own dedicated designer of external packaging design, production conditions and arrangements for making the production of the factory clearance, so in terms of packaging lines to color are very clear, milli unambiguous.

     2, seal word is clear: In the INA bearings body words will be printed on the brand, label and so on. Font is very small, but most are factory produced using Seal technology, but without the heat-treatment is carried out before the word pressure, so the font was small, but a deep concave, very clear. The font counterfeit products not only blurred, because the rough printing technology, fonts floating on the surface, and some can even be easily wiped off by hand.

     3, whether there is a hybrid ring: left hand holding stainless steel sleeve bearing the body, right hand to rotate toggle coat, listen to whether there is a hybrid ring. As most of the counterfeit products behind the production conditions, completely hand-mill operation in the production process will inevitably distracted by a class of impurities in the sand, hidden in INA bearings body, so the rotation will be issued when hybrid ring. This is strictly enforced and production standards, and with the machine operation is the biggest difference between brands.

     4, if there is muddy surface traces of oil: This purchase stainless steel bearings should pay special attention. Because of the current anti-rust technology is not particularly home, so the INA bearing body rust treatment can easily leave traces of oil thick, sticky thick stick in your hand, while the foreign original bearing almost invisible to rust oil traces, it touches especially careful expert said bearing smells kind of taste, is certainly under anti-rust oil, but do not see it.

     5, chamfering is uniform: the so-called bearing chamfer, which is horizontal plane and the vertical plane of the junction, counterfeit bearings as restrictions on production technology, in which the corners of the site handled unsatisfactory.

     INA bearing materials metallurgical quality of early bearing failure of the main factors. As metallurgical techniques (such as bearing steel vacuum degassing, etc.) progress, improve the quality of raw materials. Raw material quality factors in a stainless steel bearing failure analysis in the proportion has decreased significantly, but it is still bearing bearing failure is one of the main factors.
