Analysis of reasons for premature damage to imported SKF bearings



One, improper installation (about 16%)

1, the use of brute force when the bearing is installed, with the hammer directly hit the skf bearing the greatest damage to the bearing; is the main cause of deformation.

2, the installation is not in place, the installation is biased or not mounted to the bearing position, resulting in bearing clearance is too small. The inner and outer rings are not in the same center of rotation, resulting in different hearts.

Recommendation: Select the appropriate or professional bearing installation tool and use a special instrument for inspection after installation.

Second, fatigue (about 34%)

Fatigue damage is a common damage to SKF bearings. Common causes of fatigue damage may be: long-term overload bearing operation; not timely maintenance; improper maintenance; equipment aging.

Third, pollution (about 14%)

Contamination can also lead to premature failure of FAG bearings. Contamination refers to dust, metal chips, etc. entering the inside of the bearing. The main reasons include: premature opening of NSK bearing packaging before use, resulting in pollution; installation of the working environment is not clean, causing pollution; bearing the working environment is not clean, pollution of the working medium.
