plain cylindrical journal bearing

When a journal bearing begins rotating, there is very little lubricant between the hole and shaft at the contact point, H0, and rubbing occurs. Therefore much friction needs to be overcome when starting a hydrodynamic journal bearing. When the bearing has reached sufficient speed, the lubricant begins to wedge into the contact area and hydrodynamic lift is attained.
A journal bearing has hydrodynamic lubricating layer.
