What Causes Premature Failure And How To Improve Bearing Life?

Dec 11, 2017

In the same working conditions and consistent appearance of the bearing, the actual life is very different. what causes it? Summarized the following points:


First, improper installation (about 16%)


1, the installation of excessive force, which hammer percussion bearings on the bearing damage is the largest; is also the main reason for causing deformation.


2, the installation of a deviation or not installed in the bearing, resulting in bearing clearance is too small. Inside and outside the ring is not in the same center of rotation, resulting in different hearts.


Recommendation: Choose the appropriate or professional bearing installation tools, then use special equipment to test.


Second, pollution (about 14%)


Pollution can also lead to premature bearing damage, pollution refers to the dust, metal debris into the bearing inside. The main reasons include: pre-use to open bearing packaging premature, causing pollution.


Recommendations: It’s better not to open the bearing packaging before using ; keep the installation environment clean,clean the used bearings; enhance the bearing seal.

Third, badness lubrication (about 50%)


According to the survey, badness lubrication is one of the main causes of premature bearing damage. Including replenish lubricants or lubricant oil not in time; lubricants or lubricants not in place; improper lubricant or lubricant selection; incorrect lubrication methods, etc.


Recommendation: Choose the correct lubricant or lubricant and use the correct lubrication method.


Fourth, fatigue (about 34%)


Fatigue damage is a common way of bearing damage. Common causes of fatigue damage may be: long-term bearing overload operation; not timely maintenance; improper maintenance; equipment aging.


Recommendation: Choose the appropriate type of bearing, regular replacement of fatigue bearings in time.
