The supplier should not be blamed for bearing problems

The early damage of bearings may be caused by a variety of comprehensive factors. When there is a problem with the bearing, we should check it according to the damage possibility of this article, so as to solve it. Don't blindly investigate all the responsibilities of suppliers.

1. Improper installation (about 16%)

1) When installing, use brute force and directly knock the bearing with a hammer to cause the greatest damage to the bearing; Is the main cause of deformation.

2) The installation is not in place, there is deviation in the installation or it is 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 misalignment.

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

2. Poor lubrication (about 50%)

According to the investigation, poor lubrication is one of the main reasons for premature bearing damage. The main reasons include: failure to fill lubricant or lubricating oil in time; Lubricant or lubricating oil is not filled in place; Improper selection of lubricant or lubricating oil; Incorrect lubrication method, etc.

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

3. Pollution (about 14%)

Pollution will also lead to premature damage of bearings. Pollution refers to the entry of dust, metal chips, etc. into the bearing. The main reasons include: opening the bearing package too early before use, resulting in pollution; The working environment is not clean during installation, causing pollution; The working environment of the bearing is not clean, and the working medium is polluted.

Suggestion: it is best not to unpack the bearing before use; During installation, keep the installation environment clean and clean the bearings to be used; Strengthen the sealing device of the bearing.

4. Fatigue (about 34%)

Fatigue damage is a common damage mode of bearing. The common causes of fatigue failure may be: long-term overload operation of bearings; Not repaired in time; Improper maintenance; Equipment aging, etc.
