A new film thickness and friction coefficient measurement system was developed based on the thrust rolling bearing structure.At low speeds,the film thickness and friction coefficient can be measured simultaneously in this measurement system,and at high speeds,the film thickness can be measured under the mode of cage fixation and glass disc rotation,the friction coefficient can be measured under the mode of cage free rotation and glass disc fixation.The variations of film thickness with entrainment velocity at different loads were measured and the quantitative comparisons between single-contact and multiple-contact were given,which validated the availability and reliability of the system.The measured friction coefficient curves indicate there exists a slip between the glass disc and the rolling element.The new system provides a method to evaluate lubricant properties and rolling bearing performance.
