Under a light load, the operating state of rolling bearing progresses into the fluid-film lubrication from the rolling contact between rolling element and raceway according to the increase of the rotating speed. A hydrodynamical Theory of fluid-film lubrication of cylindrical roller bearing was reported before by Buche. But the viscosity change due to pressure was not taken in his theory, regardless of the viscosity changes according to the change of oil film pressure actually. Then the fluid lubrication of cylindrical roller bearing has been investigated theoretically under the consideration of relationship between viscosity and pressure in this paper. The load capacity of the bearing increases greatly by the change of viscosity due to pressure, besides the fluid friction of the bearing calculated theoretically coincides well with the frictional resistance obtained experimentally.
