Deep groove ball bearings are precision parts, which requires a very cautious attitude in the use of that change is the use of high-performance deep groove ball bearings, if used improperly, can not achieve the desired performance results, and easy to make deep groove ball Bearing damage. Therefore, the use of deep groove ball bearings should note the following:
First, to maintain the deep groove ball bearings and the surrounding environment clean
Even if the naked eye can not see the dust into the deep groove ball bearings, deep groove ball bearings will increase the wear, vibration and noise.
Second, the use of installation to carefully
Does not allow strong punching, hammer is not allowed to directly hit the deep groove ball bearings, does not allow the transfer of pressure through the rolling body.
Third, the use of appropriate and accurate installation tools
Try to use special tools, try to avoid the use of cloth and short fiber and the like.
Fourth, to prevent corrosion of deep groove ball bearings
Direct hand to take deep groove ball bearings, it is necessary to fully wash away the hands of sweat, and coated with high-quality mineral oil after the operation, especially in the rainy season and summer to pay attention to rust.
However, under some special operating conditions, deep groove ball bearings can be obtained longer than the traditional calculation of life, especially in the case of light loads. These special operating conditions are surface damage that can be caused when the rolling surfaces (rails and rolling elements) are effectively separated by a lubricating oil film and the contaminants are restricted. In fact, under ideal conditions, the so-called permanent deep groove ball bearing life is possible.
5, deep groove ball bearing life
Therefore, in the calculation of the size of deep groove ball bearings, the word "life" must be more clearly defined. The general information provided about the basic dynamic load rating is based on a sufficiently large number of identical deep-groove ball bearings on the surface, with 90% of the time being able to achieve an over-life.
Different Definitions of Deep Groove Ball Bearing Life. One of them is "working life", that deep groove ball bearings in the actual working conditions, the actual failure before the life. It must be noted that the life of individual deep groove ball bearings can only be predicted by statistical methods. The life calculation is only about 90% of the reliability of the deep groove ball bearing groups and certain procedures. In actual use the fault is usually not caused by fatigue, the more the situation is pollution, wear, misalignment, corrosion caused by, or cage, lubricant or seal caused by failure.
