A system of lubrication in which the shape and relative motion of the sliding surfaces causes the formation of a fluid film having sufficient pressure to separate the surfaces.
A type of lubrication effected solely by the pumping action developed by the sliding of one surface over another in contact with an oil. adhesion to the moving surface draws the oil into the high-pressure area between the surfaces, and viscosity retards the tendency to squeeze the oil out. if the pressure developed by this action is sufficient to completely separate the two surfaces, full-fluid-film lubrication is said to prevail.
Often referred to as “full film lubricant”; a film of oil or other fluid completely separates moving components under load, thus maintaining low friction and eliminating wear.
