Cavitation erosion

• Severe damage to complete bearing area.  
• Cavities are usually around at low pressure areas i.e. oil groove or oil holes.  
• Caused by an implosion of gas or air bubbles released from a lubricating oil film under particular  conditions  
• The pressure set up locally during theses implosions are very high , possibly 220 bar & may cause  a pitting / cavitation
•   Prevention – May be reduced by viscous oil because of damping effect high viscous oil &  viscosity must be in limit.
