Bearing Damage Index
The vast majority of fluid film bearings give excellent service over long periods of time. When bearings do suffer damage, the cause may be obscure. Often, damage is the result of several failure modes combined.
The bearings themselves are often blamed, but while faulty design or manufacture of the bearings may be responsible, the cause is more frequently external to the bearing.
Identify Problems – and Solutions
This Bearing Damage Index is intended to inform operators regarding the likely causes of bearing damage and to identify possible responses and solutions.*
The final decision on how to address bearing damage must be based on the nature and severity of the damage and on the significance of the type of damage. As each application’s operating conditions are unique, decisions should be made in partnership with qualified engineers.
Types of Bearing Damage
