|A, improper installation (about 16%)|
A bearing installed using brute force, a direct hit with a hammer on the bearing SKF bearings greatest harm; was the main cause deformation.
2, the installation is not in place, install a deviation or not attached to the bearing position, causing the bearing clearance is too small. Inner and outer rings are not in the same center of rotation, resulting in different heart.
Recommendation: Select the appropriate or professional bearing installation tool, use special detection equipment installed.
Second, fatigue (about 34%)
Fatigue damage is a common way of SKF bearings. Common fatigue failure may be due to: bearing long-term overload operation; did not timely maintenance; improper maintenance; equipment aging.
Third, pollution (about 14%)
Pollution can lead to premature failure of FAG bearings, pollution is a dust, metal shavings from entering the bearing. The main reasons: to open prematurely before using NSK Bearings packaging, pollution; installation dirty work environment, causing pollution; bearing dirty work environment, the working medium pollution.
