Abstract

A method for lubricating a rolling element bearing by an ultra low viscosity volatile fluid comprises injecting a liquefied fluid flow into the bearing, lubricating rolling contacts between the rings and the rolling elements of the bearing by the liquefied fluid, providing a flow restriction for the liquefied fluid so as to maintain at least part of the fluid at a pressure which is above the evaporation pressure which is defined by evaporation of the fluid at the temperature or temperatures which prevail(s) in the bearing.
