Bearings are an important part of hot water boilers. Its main function is to support the rotating body of the hot water boiler, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearing wear is normal. If the wear is abnormal, check it, find the cause and replace it in time. The main reason for wear is that the clearance is not adjusted properly, the working surface and the bearing are not concentric, which is the lack of lubricating oil.

       Bearing damage is one of the direct causes of bearing wear, which is caused by bearing ablation and damage. At the moment of damage, a high temperature will appear at the mating surface, and the inner ring and the bearing surface will rotate relative to each other, which will directly lead to the wear of the bearing position.
       For bearings with serious wear, the traditional repair methods include repair welding machine processing repair process and electric brush plating repair process. However, there is a problem of thermal stress in the repair welding process itself, which is easy to cause bending and deformation of the shaft, and may cause cracks in the welding part, resulting in the risk of interrupting the shaft during the use of the hot water boiler; the brush plating process of the brush plating process is subject to wear and tear. Restriction, the general brush plating thickness is less than 0.2mm.
