      Bearing Failure: Wear

      Damage Condition

      Wear is surface deterioration due to sliding friction at the surface of the raceway, rolling elements, roller end faces, rib face, cage pockets, etc.

      Possible Causes可能原因 進(jìn)入碎屑 銹蝕和電蝕逐漸侵害 潤(rùn)滑不好  滾動(dòng)體不規(guī)則運(yùn)行造成的滑動(dòng)

      • Entry of debris

      • Progression from rust and electrical corrosion

      • Poor lubrication

      • Sliding due to irregular motion of rolling elements

      Countermeasures

      • 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
