Damage Condition Possible Causes Countermeasures

Creep is the phenomenon in bearings where relative slippage occurs between fitting surfaces and thereby creates a clearance between them surface. Creep causes a shiny appearance, occasionally with Scoring or Wear.

Insufficient interference or loose fit
Insufficient sleeve tightening

  • Check the interference, and prevent rotation
  • Correct the sleeve tightening
  • Study the shaft and housing precision
  • Preload in the axial direction
  • Tighten the raceway ring side face
  • Apply adhesive to the fitting surface
  • Apply a film of lubricant to the fittingsurface
