Hydrodynamic, Hydrostatic, and Roller Bearing Compared
Bearings that interest us are in 3 categories: Hydrodynamic, Hydrostatic, and Roller. Hydrodynamic and the hydrostatic make use of a phenomenon called the Wedge Effect. This wedge effect is a self-generated pressure that is developed when a film of oil between a moving shaft and a collar or sleeve is forced through a wedge shaped passage.
