  • Lubricant Failure = Bearing Failure | Machinery

    2020-8-16 · Rolling element bearings are highly reliable components, and the vast majority of bearings will outlive the equipment on which they are installed. However, while bearings account for a relatively small percentage of all equipment breakdowns, they do fail occasionally. And when they fail, it is usually a critical event, resulting in costly repair and downtime.
