The most common problem with bearings

The early damage of bearings may be caused by a variety of combined factors. When there is a problem with the bearing, you can refer to the possibilities mentioned in this article to investigate and find a solution according to the cause.

1. Improper installation (about 16%)

1) Use brute force during installation. Directly hitting the bearing with a hammer will cause the greatest damage to the bearing, which is the main cause of deformation;

2) The installation is not in place, the installation is deviated or not installed in the bearing position, resulting in too small bearing clearance. The inner and outer rings are not in the same rotation center, resulting in different centers;

Suggestion: choose appropriate or professional bearing installation tools, and use special instruments to test after installation.

2. Poor lubrication (about 50%)

According to the survey, poor lubrication It is one of the main reasons for premature bearing damage. The main reasons include: not adding lubricant or lubricating oil in time; not filling lubricant or lubricating oil in place; improper selection of lubricant or lubricating oil; incorrect lubrication method, etc.

Suggestion: choose the correct lubricant or lubricating oil, and use the correct lubrication and filling method.

3. Contamination (about 14%)

Contamination can also lead to overheating of bearings Early damage, contamination means that sand, metal chips, etc. enter the inside of the bearing. The main reasons include: prematurely opening the bearing package before use, causing pollution; unclean working environment during installation, causing pollution; unclean working environment of the bearing, pollution of the working medium, etc.

Suggestion: It is best not to unpack the bearing before use; keep the installation environment clean during installation, and clean the bearing to be used; strengthen the sealing device of the bearing.

4. Fatigue (about 34%)

Fatigue damage is common in bearings damage method. Common causes of fatigue damage may be: long-term overload operation of bearings; failure to maintain in time; improper maintenance; equipment aging and so on.

Suggestion: choose the appropriate bearing type, and replace the fatigue bearing regularly and in time.

The above are the most common causes of early bearing damage. There are many reasons for early bearing damage. The above are the main reasons for consideration, and sometimes may be comprehensive reasons. If the bearing is selected correctly, the installation method is in place, and the lubrication method and lubricant are selected correctly, the bearing can work normally for a long time.

So the early damage of the bearing may be caused by a variety of comprehensive factors. When there is a problem with the bearing, we should check it according to the possibility of damage in this article, so as to solve it. Do not blindly investigate all the responsibilities of the supplier.
