Poor lubrication (about 50%)
According to the survey, poor lubrication is one of the main causes of premature bearing damage. The main reasons include: failure to fill lubricant or lubricating oil; lubricant or lubricating oil is not filling in place; selection of lubricants or lubricant improper lubrication is not accurate and so on.
Suggestion: choose the right lubricant or lubricating oil, lubricating filling mode accurately.
Improper installation (about 16%)
1, the installation to use brute force, direct percussion with a hammer FAG bearing the greatest damage to the bearings are the main cause of deformation.
2, the installation is not in place, install a biased or not loaded to bearing, resulting in bearing clearance is too small. The inner and outer rings is not uniform rotation center, resulting in different heart.
Recommendation: select the appropriate or professional bearing installation tool, installed special equipment to use test.
Tired (about 34%)
Fatigue damage is a common damage mode bearing. Fatigue failure of the common reasons may be: Bearing long-term overload operation; not timely repair; repair improper; aging equipment etc..
Pollution (about 14%)
Pollution can also cause the FAG premature bearing damage, pollution is refers to dust, metal scraps into the bearing internal. The main reasons include: before use too early to open the FAG bearing package, causing pollution; installation work environment is not clean, pollution; bearing working environment is not clean, the working medium pollution.
Suggestion: before use, it is best not to open the bearing packaging; install to keep the environment clean installation, cleaning bearings to be used; to enhance the bearing seal.
Summary of the FAG bearing early damage cause I wish everybody should pay attention to.
