Understanding Journal Bearings

An oil pressure film develops with equal and opposite force vectors to the applied load. One surface drags the lubricant, usually an oil, into a converging gap. As the space available in this gap decreases, the fluid develops a pressure gradient, or pressure hill. As the fluid leaves the gap, the high pressure helps expel it out the other side.
