This study presents a comprehensive technique, which could be applied to almost any rotating equipment to identify and diagnose journal bearing problems that relate to metal-to-metal bearing suiface contact. Orbital measurements that describebearing parameters in different modes of operation were experimentally obtained and analyzed. Such parameters may include: attitude angle, minimum oil film thickness, and the possibility of metal-to-metal rubbing occurrence. The general outline of thepresented experimental technique was substantiated using the Raimondi-Boyd well-documented design charts and good correlation between experimental and analytical results was obtained.
