Succeeding to the research of 1st report^<(1)>, the cooling effect of air and the influence of viscosity of oil and rotating speed upon the performances or preloaded ball bearing operated at a high speed under fog lubrication have been investigated. The experimental results obtained are as follows : The tendency of bearing temperature rise under fog lubrication may be explained by the ordinary formula of heat conduction with cooling velocity index. According to the increase of rotating speed of ball bearing, the bearing temperature rises rapidly, while the coefficient of friction increases rather gradually, and the increasing rates of temperature rise and coefficient of friction decrease as the rotating speed increases. The coefficient of friction and bearing temperature change are directly proportional to the oil viscosity at the running temperature of bearing. After all, it is concluded that the fog lubrication contains the oil film lubrication very much in spite of very few amount of oil and the effect of viscosity is predominant.
