Floating bush bearings are widely used as bearings for high-speed rotating turbochargers because the double oil film formed inside and outside of the floating bush can reduce friction and vibration. However, it is difficult to find the oil film formation conditions, and many aspects of its characteristics remain unexplained. Under this background, the authors have attempted to observe the double oil film of the floating bush bearing utilizing X-ray CT. In this study, the observation of the double oil film using X-ray CT was conducted, focusing on bushes with different clearance ratios and conducting comparative experiments on their characteristics.
