Some of the ways to distinguish INA bearing quality stainless steel

Proper material selection is still is INA bearing failure analysis factors must be considered. The main task of the bearing failure analysis, which is based on a lot of background material, analyze data and failure forms, find out the main factors of stainless steel bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden. Installation conditions is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and early failure. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. 1, the outer packing is clear: in general, are factory brand has its own professional design external packaging design, and arrange production with the conditions of the factory production, so the packing is very clear from the lines to the colors & shy; , unequivocally. 2, seal character is clear: on the INA bearing body printed with brand, label, etc. Font is very small, but is produced by the factory are mostly use seal technology, and before without overheating treatment of words, so the font although small, but concave & shy; Deep, very clear. And counterfeit products font instead of fuzzy, because of printing technology coarse, font float to the surface, in some cases can be easily erased by hand. 3, if there is a complex ring: stainless steel bearing body with his left hand, right hand toggle coat to make it spin, listen to its hybrid ring. Due to the backward production conditions most of the counterfeit products, fully manual mill operation, in the process of production inevitably mixed into the sand & shy; Kind of impurity, hidden in the INA bearing, so makes a noise when rotating ring. This is and strict production standards, and use machine operation are factory is the biggest difference between brands. 4, if there is a muddy surface oil stains, it should pay special attention to when buying stainless steel bearing. Due to the current domestic antirust technology is not particularly home, so the INA bearing body the antirust processing and it is easy to leave a thick oil stains, holding the stick & shy; Thick thick, while the foreign original bearing can hardly see the trace of anti-rust oil, is particularly careful expert said bearing smell a smell, must be under the anti-rust oil, just can't see. 5, chamfering whether uniform: so-called bearing chamfer, namely horizontal plane and vertical plane junction, counterfeit bearings because of the limitation of production technology in the area of the fringes is handled. INA bearing materials of metallurgical quality were the main factors influencing the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in stainless steel bearing failure analysis share has declined obviously, bearing but it is still one of the main influence factors of bearing failure.
