This drawing illustrates the relationship of the oil film to the bearing journal and the bearing. The film of oil can range from 0.001 to 0.0 during operation, depending on the load, the VI rating of the oil, and the clearance of the bearing (the greater the clearance in the bearing, the greater the opportunity to lose the wedge and have metal-to-metal contact). This can be due to oil leakage past the bearing and the oil pump's ability to distribute oil to the bearing.
