Wear

Damage ConditionPossible CausesCountermeasures
Wear is surface deterioration due to sliding friction at the surface of the raceway, rolling elements, roller end faces, rib face, cage pockets, etc.
  • Entry of debris
  • Progression from rust and electrical corrosion
  • Poor lubrication
  • Sliding due to irregular motion of rolling elements
  • Improve the sealing mechanism
  • Clean the housing
  • Filter the lubrication oil thoroughly
  • Check the lubricant and lubrication method
  • Prevent misalignment

Wear 1

Part: Inner ring of a cylindrical roller bearing
Symptom: Many pits occur due to electrical corrosion and wave-shaped Wear on raceway surface
Cause: Electrical corrosion

Wear 2

Part: Outer ring of a spherical roller bearing
Symptom: Wear with a wavy or concave-convex texture on loaded side of raceway surface
Cause: Entry of debris under repeated vibration while stationary

Wear 3

Part: Inner ring of a double-row tapered roller bearing
Symptom: Fretting Wear of raceway and stepped Wear on the rib face
Cause: Fretting progression due to excessive load while stationary

Wear 4

Part: Tapered rollers of damage “Wear 3”
Symptom: Stepped Wear on the roller head end faces
Cause: Fretting progression due to excessive load while stationary
