Bearing failure reason analysis

Bearing failure reason analysis
First, improper installation (about 16%)
1, installed using brute force, a direct hit with a hammer on the bearing bearing greatest harm; It is caused by deformation of the main reasons.
2, the installation is not in place, install a deviation or not attached to the bearing position, causing the bearing clearance is too small. Inner and outer rings are 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, poor lubrication premature bearing damage is caused by one of the main. Main reasons include: not timely filling lubricant or lubricants; lubricants or lubricants are not filling in place; lubricant or lubricant improper selection; lubrication incorrectly so.Recommendation: Select the correct lubricant or lubricating oil, used lubricant filling the correct way.

Third, pollution (about 14%)
Pollution can lead to premature bearing damage, pollution is a dust, metal shavings from entering the bearing. Main reasons include: bearing packaging prior to use to open prematurely, 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; installed to keep the environment clean installation of bearings to be used for cleaning;enhanced bearing seals.
Four, fatigue (about 34%)
Fatigue damage is a common way of bearing. Common fatigue failure may be due to: bearing long-term overload operation; did not timely maintenance; improper maintenance; equipment aging.Recommendation: Select the appropriate bearing type, regular and timely replacement of fatigue bearings.These are the most common types of causes of damage caused by early bearing; bearing early damage caused by many reasons, these are the main reasons to consider, it may sometimes be comprehensive reasons. If the correct bearing selection, installation properly in place, select the correct lubrication and lubricants, bearings can work very often time-consuming.
