Beware the Four Levels of Inadequate Bearing Lubriion

Most bearings―some 80 to 90%―use grease as a lubricant, and most bearing damage is caused by inadequate lubriion, where an insufficient amount of grease separates the rolling and sliding contact surfaces during service. This can result in progressive levels of bearing damage and mounting risk to safe and efficient operations.
