And the reasons for bearing damage

Most damage to bearing damage can be divided into two categories: pre-run damage and run damage. Run before damage occurs during installation or before damage occurs while running in the bearing is running.

Before running the cause of damages:

Incorrect shaft and housing complexes;

Shaft and bearing in a bearing mating surface defects;

Static misalignment;

Installation;

Current through the bearing (high voltage)

Transportation, handling and storage;

Run damage causes:

Fatigue;

Invalid lubrication;

Invalid seal;

Vibrations (fretting corrosion);

Run misalignment;

Current through the bearing (current leakage);
