EN In the paper presented are capabilities of advanced rotary machinery diagnostics based on the analysis of trajectories of slider bearing journals. Outlined and characterized have been the categories of rotary machine malfunctioning, which can be detected and discriminated on the basis of images of the journal center trajectory. Discussed have been these elements of trajectories, which bear information about the dynamic state of the machine and which can contribute to differentiation of the machine defects. Principles of diagnostics of the machine state have been analysed from the point of view of relations between the trajectory feature and the rotor dynamic state. Presented problems are based on author's own expertise and have been illustrated by sample images stemming from author's own experimental investigations as well as numerical simulations conducted using own computer codes. The material contained in the paper can be helpful in practical diagnostic applications.
