First, improper installation (about 16%)
(1) the use of brute force when installing a direct hit with a hammer bearing the greatest force on the bearing damage is the main cause of deformation.
(2) the installation is not in place, install a deviation or mounted to the bearing position, causing the bearing clearance is too small. Inside and outside the ring is not in the same center of rotation, resulting in different heart.
Recommendation: Select the appropriate or professional bearing installation tool, use special detection equipment installed.
Second, poor lubrication (about 50%)
According to the survey, one of the main causes of poor lubrication bearing premature failure. The main reasons: not timely filling of lubricant or oil; lubricants or lubricants are not filling in place; improper lubricant or lubricant selection; incorrect lubrication and so on.
Recommendation: Select the correct lubricant or lubricant, lubricant filling the correct way.
Third, pollution (about 14%)
Pollution can also cause premature bearing damage, pollution refers to dust, metal shavings from entering the bearing.
The main reasons: the use of open prematurely before bearing packaging, causing pollution; installation dirty work environment, causing pollution; bearing dirty work environment, the working medium pollution.
Recommendation: Do not open before using the best packaging bearing; a bad environment clean install when installing the bearing to be used for cleaning; enhanced seal bearing.
Fourth, fatigue (about 34%)
Bearing fatigue damage is a common way of damage. Common causes of fatigue failure may be: bearing long-term overload operation; not timely maintenance; improper maintenance; equipment aging.
Recommendation: Select the appropriate bearing type, regular and timely replacement of bearing fatigue.
These are the most common cause of early bearing damage caused several; cause early bearing failure are many, these are the main reasons to consider, it may sometimes be comprehensive reasons. If the correct bearing selection, installation place, lubrication and lubricants to choose the right bearing is normal.
