    bearing can perform before incipient flaking occurs. This does not mean to say that the bearing cannot be used after then. Flaking is a relatively long, drawn-out process and makes its pres-ence known by increasing noise and vibration levels in the bearing. There-fore, as a rule, there is plenty of time to prepare for a change of bearing.
