Bearings are precision parts, which requires the use of a fairly cautious attitude that change is the use of high-performance bearings,
If used improperly, they can not achieve the expected performance results, and easy to bearing damage. Therefore, the use of the bearings should be
Note the following:
 
First, to maintain the bearing and its surroundings clean
 
Even smile invisible dust into the bearing, will increase the bearing wear, vibration and noise.
 
 
Second, use the installation should carefully
 
Does not allow a strong punch, does not allow a direct hit with a hammer bearing, does not allow pass through the rolling pressure.
 
 
Third, the use of appropriate and accurate installation tool
 
Make use of special tools; try to avoid using fabric and staple fibers and the like.
 
 
Fourth, to prevent corrosion of bearings
 
Direct hands to take bearings, to fully wash hands sweat, and coated with high-quality mineral oil before the
Rainy season and summer with particular attention to rust.
However, in some special operating conditions, the bearings can get a longer life of the conventional calculation, especially in the light
Load conditions. These special operating condition is, when the rolling surface (track and rolling member) efficiently by a lubricant film
Ground segregation and restrictions pollutants may lead to surface damage. In fact, under ideal conditions, the so-called permanent bearing Life
Life is possible.
 
 
Bearing life
 
The life of rolling bearings in revolutions (or a certain speed the number of hours worked) Definition: a shaft within this life
Order shall in any of its rolling bearing ring or fatigue damage occurs on the initial (spalling or defect). But both in the laboratory
Test or in actual use, can clearly see, in the same operating conditions the appearance of the same bearing, the actual life of a large
Are not the same. In addition there are a number of different definitions of the bearing "lifetime", one of the so-called "working lives", which means
A bearing damage can be achieved before the actual life is determined by wear and tear, damage is usually not caused by the fatigue, but by wear and tear,
Corrosion, seal damage and other causes.
 
 
Why bearings will wear damage
 
Only a portion of the bearing damage in practical applications.
 
Most of the bearings pumping bad for many reasons - beyond the original estimate of the load, non-effective seal tight with the
Caused by too small bearing clearance and so on. Any one of these factors has its special damage factor, and will leave a special type of damage
Therefore, to view damaged shaft bearing, in most cases you can find its possible cause, generally speaking, one-third of
Bearing damage due to fatigue damage, arising out of the other one-third of poor lubrication, the other third conduction due to contaminants
Improper handling or installation into the bearing.
 
 
However, these types of damage are not related with the industry. For example, most of the pulp and paper industry is due to poor lubrication or semi-
Bearing damage caused by pollution and not due to material fatigue.
