What caused the early damage to the bearing?2016-10-13
1. Improper installation (about 16%)
Use brute force during installation and directly hit the bearing with a hammer to cause the most damage to the bearing; it is the main cause of deformation.
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 at the same center of rotation, causing eccentricity.
Suggestion: Choose appropriate or professional bearing installation tools, and use special instruments to test after installation.
2. Poor lubrication (approximately 50%)
According to investigations, poor lubrication is one of the main causes of premature bearing damage. The main reasons include: not filling 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 filling method.
3. Pollution (about 14%)
Pollution can also cause premature bearing damage. Pollution means that sand, metal shavings, etc. enter the bearing. The main reasons include: opening the bearing packaging prematurely before use, causing pollution; the working environment is not clean during installation, causing pollution; the working environment of the bearing is unclean, working medium pollution, etc.
Recommendations: It is best not to unpack the bearings before use; keep the installation environment clean during installation, clean the bearings to be used; strengthen the sealing device of the bearings.
4. Fatigue (about 34%)
Fatigue damage is a common way of bearing damage. The common causes of fatigue damage may be: long-term overloading of bearings; failure to repair in time; improper maintenance; equipment aging, etc.
