%X Some selected issues on the continuity of motion of rolling elements observed with the FDM-A1 diagnostic method [1] have been given consideration. A formula for the ratio of angular velocities of the cage and the bearing journal during the process of perfect rolling (i.e. with no spins of rolling elements against the bearing race) has been proposed. The ratio has been labelled by the Authors as a ¡®coefficient of the rolling¡¯. Included are results of the computer-aided simulation of how changes in the geometry of some components of a rolling bearing affect dynamic properties thereof. A simple method to conduct preliminary checks of the correctness of the rolling motion of rollers of a rolling-element bearing has also been mentioned. This method has been successfully used by the Authors. Types of the rolling characteristics resulting from the tests with the FDM-A method have been described and correlated with particular types of mechanical failures to the rolling-element bearings and the compressor-turbine sub-system of a turbine engine.
