In high-speed turbines the lubricating oil will be at the sides and there is metal to metal contact when turbine at rest. When the turbine speeds up there is pressure pushing the oil through the metal to metal contact. When turbine finally achieves its speed the oil film breaks the barrier and it takes the load on itself. This is hydrodynamic lubrication.
