FALSE BURNELLING F007
The bearing races show a series of dents or impressions where the balls have forced themselves into the hard metal.
The term false burnelling is used because the dents were caused by vibration of the bearing when the pump was at rest and not as a result of any overloading condition.
Some people feel that the induction heaters used to expand bearings for installation can be one of the causes of false burnelling problems.
