Abstract The quantitative dependence of friction property of planar-type water-lubricated rubber bearing on spindle speed, bearing pressure and load resulted by whirling vibration was investigated based on friction torque measurement and which was presented mathematically providing an important guarantee for prediction of dynamic response in system excited by bearing friction. Experiment results show that friction coefficient of water-lubricated rubber bearing decreases as spindle speed increases; the friction characteristic under fully run state plays more sensitive to variation of spindle speed than it being in the initial phase; bearing pressure has little influence on friction coefficient if it has been smoothed; the effect of load resulted by whirling vibration mainly plays a part in friction coefficient when the rotor speed is located at intermediate level.
