Damage analysis


All machine components undergo change during use. Running marks appear which usually have little or no effect on their serviceability. These marks can reveal a great deal about whether operating conditions for the bearing are acceptable. They do not indicate that any damage is present.

The different types of damage can be subdivided into the following groups.

  • Fatigue
  • Wear
  • Corrosion und erosion
  • Overload

The causes of damage can be determined by carrying out a detailed analysis of damaged bearings in the laboratories of the Schaeffler Group. In a subsequent step, measures can be derived for preventing the damage in future.
