The so-called fracture means that a small part of the bearing is broken due to the impact or excessive load applied to the local part of the rib or the roller angle of the raceway wheel. The reason for this is that the bearing was hit during installation. The load is too high. Poor use such as falling. Corresponding measures improve the installation method (shrink-fit, use suitable tool clips). Correct load conditions. Cylindrical roller bearings are in place so that the ribs are supported. First of all, if the structural design is reasonable and advanced, it will have a long ntn bearing life. The manufacture of bearings generally goes through multiple processing processes such as forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of each processing technology will also affect the life of the bearing. Among them, the heat treatment and grinding processes that affect the quality of the finished bearing are often more directly related to the failure of the cylindrical roller bearing. In recent years, the research on the metamorphic layer of the bearing working surface shows that the grinding process is closely related to the bearing surface quality. The metallurgical quality of ntn bearing materials used to be the main factor affecting the early failure of rolling bearings. With the advancement of metallurgical technology (such as vacuum degassing of bearing steel, etc.), the quality of raw materials has been improved. The proportion of raw material quality factor in the failure analysis of cylindrical roller bearings has dropped significantly, but it is still one of the main factors affecting bearing failure. Whether the material is selected properly is still a factor that must be considered in bearing failure analysis. The main task of bearing failure analysis is to find out the main factors causing the failure of ntn bearings based on a large number of background materials, analysis data and failure forms, so as to propose improvement measures in a targeted manner, prolong the service life of the bearing, and avoid cylindrical roller bearings. Sudden early failure occurs. Second may be excessive load (excessive preload). Speed ​​is too high. Clearance is too small. Water or other foreign objects have entered. If the above two situations are not the case, then the accuracy of the shaft and bearing housing is poor, and the deflection of the shaft is large. Seeing this, I think everyone wants to know the solution. First of all, we must study lubricants and lubrication methods, choose the right lubricant for cylindrical roller bearings, and their dosage, and correct the choice of ntn bearings. Investigate fit, bearing clearance and preload, and improve sealing arrangements. Check the accuracy of the shaft and bearing housing.
