Deep groove ball bearing is the most widely used type of bearing in the current mechanical parts. We all know that there are often some problems in the process of using deep groove ball bearings, such as frequent damage to bearings in use.

In all kinds of specific use, the casting industry is a deep groove ball bearing damage more frequently an industry, by deep groove ball bearing China official website analysis, the main reason is that the unique in the use of metallurgical machinery, continuous high temperature, high dust, heavy load, shaft widening, shaft tensile strain and so on are the main causes of deep groove ball bearing damage in advance, The service life length of deep groove ball bearings used in the casting industry is related to the maintenance times of the company's machines and then affects the company's operating income. The selection of high quality deep groove ball bearings is not only associated with the company's product cost, maintenance cost, replacement period, product quality, equipment utilization rate and staff utilization rate, but also can reduce the equipment failure rate of the machine and reduce unnecessary production capacity consumption. Is an essential condition for the development of the industry.

How to reduce the advance damage of deep groove ball bearings in operation should be a problem that many people pay more attention to.

The main manifestations of deep groove ball bearing damage are nothing more than inner and outer fracture, rolling body crushing and tooth reguard fracture, especially in the casting industry, bearing damage is more common, there are many reasons for damage, such as the installation and positioning is not close to the bearing rolling on the shaft or in the seat hole, too small clearance causes too much friction and heating of the bearing, Excessive load or relatively large vibration load, impact load, bearing sealing caused by the residue entry, etc., are all important reasons for deep groove ball bearings to damage and break in advance. The solutions are as follows: Pay attention to the clearance of the internal structure of the bearing and a certain radial or axial amount of movement, especially the clearance after assembly. For places with light load and continuous high temperature, we must ensure that the internal structure of the bearing has a certain clearance after installation, and ensure that after working for a period of time, with the rise of bearing temperature, the internal structure of the bearing will not be too tight and hot due to too much tension between the rolling body and the dovetail guide rail. Lead to bearing invalid in advance. Improving the sealing effect and filling the wetting immediately on time can also fundamentally solve the problem of bearing damage in advance.
