First, clean the bearing and its surroundings
Even invisible dust into the bearings smile, will increase wear, vibration and noise of the bearing.
Second, when using the installation to be carefully
Allowed strong punching, does not allow a direct hit with a hammer bearing, not allowed to pass through the rolling pressure.
Third, the use of appropriate, accurate installation tool
To make use of special tools, try to avoid using fabric and staple fiber stuff like that.
Fourth, to prevent corrosion of bearings
Direct hand pick bearings, to fully wash hands sweat, and coated with high-quality mineral oil before you start working, during the rainy season and summer with particular attention to rust.
However, in certain special operating conditions, bearings can get a longer life in traditional computing, especially in the under light load conditions. These special operating conditions is, when the rolling surface (track and rolling element) are effectively separated and limit pollutants may cause damage to the surface of a lubricant film. In fact, under ideal conditions, the so-called permanent bearing life is possible.
Fifth, bearing life
Therefore, in the calculation of the bearing size, must the term "life" is more clearly defined. All information about the general basic rated dynamic load provided is based on the same surface of the bearing of a sufficiently large number, more than 90% can be achieved as the basis of life.
Different definitions of bearing life. One of them is "working life", said the actual attained before the bearings under actual working conditions, failure of life. It must be noted that individual bearing life can only be predicted by statistical methods. Bearing life calculation only for groups and reliability in terms of certain procedures, about 90%. Failures occur in actual use is not usually caused by fatigue, the situation is more contamination, wear, misalignment, corrosion caused by failure to maintain or another cage, lubricant or seals caused.
Another "life" is "the life of the agreement," the lawsuit party designated by departments or agencies to develop industry standards, and based on an assumed working load and speed conditions. This is basically all the basic bearing rating life, generally based on the experience of similar applications come dependent.
