hydrostatic film
Quick Summary
A hydrostatic film is a layer of fluid, typically oil, that separates the surfaces within a sliding bearing. This film is created by an external pumping unit that supplies pressurized oil to the bearing. This is distinct from a hydrodynamic film, which forms naturally between surfaces under specific conditions of load, speed, and fluid viscosity. Hydrostatic films are used in machine construction to reduce friction and support moving parts, allowing them to rotate or move in a straight line relative to one another. Hydrostatics itself is a branch of physics that studies fluids at rest and the pressure they exert.12
