Rolling bearing damage is disruptive, but often avoidable. The six articles in this chapter will not only present relevant types of damage and their causes, but also tips for prevention and early detection. Fatigue damage is “natural” bearing damage and occurs after reaching a fatigue life of the material. Conversely, there are a number of “unnatural” types of damage, including wear, plastic deformation, cracks and fractures, which often occur due to insufficient lubrication or contaminants in the lubricant. Corrosion usually occurs after the rolling bearing comes into contact with water or other chemical substances. You will also find an article on the subject of electro-erosion, which is understood to mean structural changes and material removal that occur due to the transfer of damaging electrical currents.
