Damage Condition

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.

Possible Causes

• Insufficient interference or loose fit
• Insufficient sleeve tightening

Countermeasures

• 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 fitting surface
