I have a part with a 4 inch precision bearing bore that has a defect in the bore due to an insert breaking, and causing a small gauge in the diameter. This means my ABEC 7 outer bearing race will not make 100% contact with the bore that it is pressed into, this bearing has small balls because the shaft is around 3 inches on the od. This is a special spindle application and will the shaft will be rotating a few thousand RPM. Does anyone have a specification of how much actual contact is needed for the bearing to run properly and not fail prematurly? Are there any articles that discuss this subject?
