Bearing failure analysis chart

Damage of bearing is classified into six main mode.

Fatigue

Repeated stresses causes change in structure.

Wear

Progressive removal of material from two sliding surface.

Corrosion

Chemical reaction on metal surface.

Electrical Erosion

Removal of material due to passage of electric current.

Plastic Deformation

This is permanent deformation.

Fracture & Cracking

Cracking-Incomplete separation of material.

Fracture-Complete separation of material.
