The failure of imported bearings is typically caused by multiple factors, and many elements involved in the production process can contribute to such failures. It can be quite challenging to identify the exact cause after analysis. Normally, it is helpful to consider and analyze the issue from two main perspectives: application-related factors and internal elements. For more general knowledge about imported bearings, you may refer to the article titled "Important Bearing Usage: Small Common Sense Collection."
Application factors involve proper device adjustment, maintenance, protection, and repair that meet technical requirements. The condition of the equipment plays a crucial role in this aspect. Improper installation of the device can lead to abnormal forces acting on the bearing, causing it to operate under unfavorable conditions and fail prematurely. It's important to monitor parameters like load, rotational speed, operating temperature, vibration, noise, and smoothness during operation. Any abnormalities should be addressed promptly through adjustments to restore normal functioning. Additionally, the quality of lubricating grease and the surrounding environment also play a significant role in the performance and lifespan of the bearing. To learn how to assess the quality of imported bearings, please read the article "How to Judge the Quality of Imported Bearings."
Internal elements primarily relate to three key factors: structural design, manufacturing process, and material quality. A well-designed structure with advanced technology can significantly enhance the bearing's service life. Bearings are usually manufactured through various steps, including casting, heat treatment, turning, grinding, and assembly. The rationality and advancement of each processing technique directly affect the bearing’s durability. Heat treatment and grinding processes, in particular, have a direct impact on the bearing’s quality. Recent research has shown that the surface deformation layer formed during grinding is closely linked to the overall quality of the bearing.
Metallurgical quality of the materials used in imported bearings was once a major factor in early bearing failures. With advancements in metallurgical technology, such as vacuum degassing of bearing steel, the quality of raw materials has improved significantly. As a result, the proportion of material-related failures has decreased, but it remains an important factor in bearing failure analysis. The appropriateness of material selection is still a critical element in determining the cause of bearing failure.
The primary goal of analyzing the failure of imported bearings is to gather and analyze a large amount of data and failure modes to identify the main causes of the failure. This enables the development of targeted improvement measures to extend the bearing's service life and prevent early failures.
