The earlier study made by Jacobson and Hamrock on t he cavitation of liquid lubricant films in a dynamically loaded journal bearing was repeated with a quartz sleeve, which was more rigid than the Pol ymethylmethacrylate (PMMA) sleeve used previously. Various improvements of t he test rig were made concomitantly so that the experimental errors could be better controlled and assessed. This paper describes the updated high-speed photography experiment and its results.
