What is a hydrodynamic lubrication bearing?

Please give me some advice! :handshake
It must be a sliding bearing, used in applications with high rotational speeds. Its principle is dynamic pressure lubrication; the liquid that provides lubrication creates high pressure in the gap, thereby serving to support the shaft.
What was said upstairs is correct; it’s a sliding bearing. As the rotating shaft turns, the lubricating oil is compressed to form an oil wedge with a certain pressure, which in turn supports the rotation of the rotor and enables it to operate smoothly.
