Rolling bearings are precision components, when in use requires a very cautious attitude, which is the use of bearing high performance, if used improperly, can't reach the expected performance results, and it is easy to make the NSK bearing damage. So, should pay attention to the following items using bearing:
1, keep the bearings and the surrounding environment clean
Even the naked eye cannot see smile dust into the rolling bearing, also will increase the wear of NSK bearings, vibration and noise.
2, use the installation carefully
Do not allow powerful punch, does not allow direct percussion with a hammer rolling bearing, not allowed to pass through the rolling pressure.
Installation tool 3, appropriate use, accurate
As far as possible the use of special tools, to avoid the use of fabric and fiber or something.
4, to prevent the bearing corrosion
The direct use of hands to pick up the rolling bearing, should wash hands sweat, and coated with high quality mineral oil before operation, during the rainy season and summer with particular attention to rust.
However, in some special operating conditions, the rolling bearing can have a longer life expectancy in traditional computing, especially in the light load conditions. These special operating conditions, when the rolling surface (track and rolling) is may cause surface damage effectively separated by a lubricant film and limit pollutants. In fact, in ideal conditions, the so-called permanent bearing life is possible.
5, the bearing life
Therefore, in the calculation of bearing size, there must be a clear definition of "life" is a word. All information is generally provides information about the basic dynamic load rating, bearing a large enough number of surface based on 90% identical, can reach more than life as the basis.
The life of rolling bearings of different definition. One of them is "working life", said bearing on the actual working conditions, failure occurred prior to actual achieved life. Must pay attention to, only the individual bearing life by statistical method for predicting. Life just on the reliability of NSK bearing group and a certain program, about 90%. Fault in actual use is usually not due to fatigue, the situation is more pollution, wear, misalignment, corrosion, or fault holder, lubricant or seal caused by.
Another kind of "life" is the "agreed life" specified by the lawsuit, departments or industry standard mechanism, and based on an assumption that the load and speed conditions. This basically is the basic rating life of all bearings, is usually defined according to similar applications to experience.
