Studies the mathematics model for calculate and analysis the high-speed bearing in order to improve the performance of high-speed bearing. According to the different work conditions, analyses the bearings ratio of revolution and rolling on the condition of elastohydrodynamic lubrication which invert from the slipping of the bearing. Based on the result of the equation, the relationship between the work conditions and ratio of revolution and rolling is deduced, a mathematic method for select the bearing in the real work and a mathematic model for the selection and optimum design of the high-speed angular contact ball bearing is provided.
