  • Bearing damage and failure analysis - SKF

    2020-12-8 · Premature bearing failure can occur for a variety of reasons. Each failure leaves its own special imprint on the bearing. Consequently, by examining a failed or damaged bearing, it is possible in the major - ity of cases to establish the root cause and define corrective actions to prevent a recur - rence. This publication is intended to provide

    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.
