INA bearing failure reasons of common considerations for analysis

Get good lubrication, if INA bearing and the correct cut off impurities and moisture, said oil seal should not wear. However, when open the bearing box, best check sliding bearing and periodically check the oil seal. Check of the condition of the near the bearing oil seal, in order to ensure that they are enough to prevent hot liquid along the axis of infiltration or corrosive liquid or gas bearing, oil seal if already wear should be replaced as soon as possible. On analyzing the factors mainly look, use, maintenance, repair and maintenance to install the related operations is not conform to the requirements of the bearing of the official. Installation conditions is to use one of the primary factor of bearing elements, INA bearings are 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, to the running of the sliding bearing of 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. In addition, for the quality of the lubricating oil and the surrounding medium test is important. By the intrinsic factors of INA bearings generally say is it's structure design, and manufacturing processes and material quality to determine its quality, below came from these three pieces of concrete analysis. First of all, reasonable structure design and equipped with advanced, just can have a long bearing life. Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. Metamorphic layer on the surface of a bearing work in recent years, research has shown that the surface quality of the grinding process and its close then, sliding bearing of the main causes of failure analysis is based on a lot of background material, analyze data and failure forms, find out the main factors of INA bearings failure, so that the improvement measures are put forward, prolonging bearing, to avoid premature failure of the attack. Bearing roller and the inner and outer ring raceway surface under the role of the periodic pulse load, resulting in a periodic change of contact stress. When stress cycles after reaching a certain value, the rolling element bearings, their work within or surface produce fatigue spalling. If the bearing load is too big, can make the fatigue. In addition, the sliding bearing installation is not straight, shaft bending, also can produce roll flaking off. INA bearing raceway fatigue spalling can reduce the running accuracy of shaft vibration and noise in the organization.
