Bearings • Journal Bearings
Journal bearings consists of a shaft rotating in the bearing with an oil layer separating the shaft and bearing. They can be lubricated hydro-dynamically or hydro-statically. Hydrostatic bearing uses an external pump to force lubricant into the system and to provide pressure that augments the pressure from the bearings rotation. Hydrodynamic bearings maintain pressure by its own shaft rotation. They require more maintenance and less wear resistance.
