This paper, co-authored by Kingsbury’s R&D Manager, Scan DeCamillo, presents experimental temperature data on the LEG (Leading Edge Groove) journal bearing for both “on pad” and “between pad” loading conditions and for different bearing clearances. The experimental results are compared with data from a computer model of the LEG bearing. In addition, the paper discusses results obtained from bidirectional testing of the LEG, and describes a technique for reducing power losses of the bearing.
