Improper installation ( about 16%)
1, the installation to use brute force, direct percussion with a hammer damage to the INA bearing the greatest; is a major 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 are not in the same center of rotation, resulting in different heart.
Recommendation: select the appropriate or INA bearing installation tool, installed special equipment to use test.
Poor lubrication ( about 50%)
According to the survey, poor lubrication is one of the main causes of INA premature bearing damage. The main reasons include: failure to fill lubricant or lubricating oil; lubricant or lubricating oil is not filling in place; lubricants or lubricant improper selection; incorrect lubrication method, etc..
Recommendation: choose the right lubricant or lubricating oil, use the correct lubricant filling way.
Pollution ( about 14%)
Pollution can also cause the INA 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 INA bearing package, causing pollution; installation work environment is not clean, pollution; INA bearing working environment is not clean, the working medium pollution.
Suggestion: before use, it is best not to open the INA bearing package; install to keep the environment clean installation, cleaning INA bearings to be used to enhance the bearing seal.
Fatigue ( about 34%)
Fatigue damage is the damage of INA bearings are common. Failure reasons of common fatigue may be: INA bearing long-term overload operation; not timely repair; repair improper; aging equipment etc..
Suggestion: choose the appropriate type of INA bearing, INA bearing fatigue timely regular replacement.
These are several of the most common causes of early damage of INA bearings; the cause of early damage of the bearing is in many aspects, the above is the main reason to consider, sometimes is reason. If the bearing selection is correct, the correct installation type in place, lubrication and lubricant selection is correct, INA bearings can work normally for a long time.
