Experimental comparison of the performance of a journal bearing with a single and a twin axial groove configuration
TLDR
In this article, an experimental assessment of a journal bearing with either one or two axial grooves located perpendicularly to the load line was performed, and it was found that under heavy loaded operation the twin groove configuration might actually deteriorate the bearing performance when compared with the single groove arrangement, namely due to uneven lubricant feed through each groove.About:
