What are the specific applications and selection points of deep groove ball bearings in different industries?

Deep groove ball bearings, as the most widely used type of rolling bearings, play an important role in many industries due to their unique structure and excellent performance. From steel smelting to energy generation, from railways and high-speed trains to household appliances, deep groove ball bearings are everywhere. When exploring its specific applications, the first thing we need to consider is the working environment and load requirements. For example, in the steel smelting industry, due to the harsh working environment, high temperature, and large dust, it is necessary to choose deep groove ball bearings with good high temperature resistance and dust prevention performance, and consider the selection of their sealing structure to ensure the stable operation of the bearings. In the field of household appliances, such as washing machines and air conditioners, although the working environment is relatively mild, there are high requirements for noise and lifespan. Therefore, low-noise and long-life deep groove ball bearings should be selected, and attention should be paid to their installation accuracy and lubrication method.

In terms of selection criteria, the first thing to consider is the bearing capacity of the bearing, namely the magnitude of radial and axial loads. Select the appropriate bearing size and accuracy level based on specific operating conditions. Secondly, the speed requirements of the bearings should be considered to ensure that the maximum speed of the selected bearings can meet the actual needs. In addition, factors such as the self-aligning performance of bearings, ease of installation and maintenance need to be considered. For occasions that require sealing, it is also necessary to choose suitable sealing structures and materials to prevent grease leakage and dust from entering.
