Partial breach and even cracks
Possible reasons
·Shock load too heavy
·Interference too big
·Big peeling off and frictional cracks
·Poor precision of the mounting side(corner circle too big)
·Frictional cracks
·Mal-applications(using copper hammer, intrusion of big foreign matter)
Solutions
·Check the application conditions
·Set proper interference and check material quality
·Improve mounting and application methods
·Prevent frictional cracks(check lubricants)
·Check bearing surrounding design
