This work is the continuation of the research concerning the dynamic model of a rotating set in turbocharger. In this model masses of rotors and a shaft have been modelled as concentrated masses. The rotating set has been propped on two supports forming lateral sliding bearings with a floating ring bearing. Each bearing is designed including floating ring bearing mass. The shaft of a rotating set spins at angular velocity omega 1 whereas a floating ring bearing spins at angular speed omega 2. A mathematical model constitutes a system of differential equations, mutually coupled. The mathematical model has been solved by determining: acceleration, velocity and displacement in each knot. The paper shows the crucial influence of a bearing relative clearance on static and dynamic properties of a rotating set in a turbocharger. The authors suggest that the rotating set works stably only in these cases as for given parameters, we choose properly oil films' geometry. In the conclusion, the authors formulate proposal that might be usefulfor the designers who deal with these types of bearings. Especially, the mathematical model o f a turbocharger rotating set, work parameters of bearing knots, researches of static and dynamic properties are presented in the paper.
