Damage Condition

Among the different types of Fretting, false brinelling is the occurrence of hollow spots that resemble brinell dents and are due to Wear caused by vibration and swaying at the contact points between the rolling elements and raceway.

Possible Causes

• Oscillation and vibration of a stationary bearing during such times as transporting
• Oscillating motion with a small amplitude
• Poor lubrication

Countermeasures

• Secure the shaft and housing during transporting
• Transport with the inner and outer rings packed separately
• Reduce the vibration by preloading
• Use a proper lubricant
