Lead to short-term use oilless bearing damage is what reason?Below small make up is to introduce the possible damage.
Customers can also be judged from the following four aspects:
1, poor lubrication (about 50%)
According to the survey, poor lubrication is one of the leading causes of premature failure of the bearing.Main reasons including: failure to refill lubricant or lubricating oil;Lubricant or lubricating oil filling in place;Lubricant or improper lubricant selection;Lubrication method is not correct, and so on.
Suggestion: to select the correct lubricant or lubricating oil, use the correct lubrication filling way.
2, fatigue (about 34%)
Fatigue damage is a common way of damaged bearing.Common fatigue failure reasons might be: bearing long-term overload operation;Not timely maintenance;Improper maintenance;Equipment aging, etc.
Suggestion: select the appropriate bearing type, timely replacement of bearing fatigue on a regular basis.
3, improper installation (about 16%)
(1) use brute force, when installation directly with a hammer percussion bearing to bearing damage;Is the main cause of deformation.
(2) the installation does not reach the designated position, install a deviation or failure to the bearing, bearing clearance is too small.Inside and outside the circle is not in the same center of rotation, resulting in different heart.
Suggestion: select the appropriate or professional bearing installation tools, installed with a special instrument to detect.
4, pollution (about 14%)
Pollution can also cause premature bearing damage, pollution is refers to the dust, metal scraps into the bearing inside.Main causes include: early to open the bearing packing before use, cause pollution;When installation work environment is not clean, cause pollution;Bearing of the working environment is not clean, working medium pollution, etc.
Suggestion: before use it is best not to unpack the bearing;Keep the installation environment clean, when installation to use the bearing in cleaning;Enhance the bearing sealing device.
These are several of the most common cause the cause of early damage of the bearing, bearing of the early damage of course the reasons are various, sometimes may be integrated.But if the bearing when use the above four aspects will completely correct, bearing still can be normal work time very often.
