Oil Flow and Temperature Relations in Lightly Loaded Journal Bearings

The trend toward higher speeds for certain types of apparatus and the decrease in weight of the moving parts which usually accompanies such a change has resulted in the application of an increasingly large number of bearings which operate at relatively high speeds and comparatively light loads. Many of these applications use sleeve-type bearings which are supplied with force-feed lubrication. In order to obtain data which may be used in designing bearings for such use, the oil flows and running temperatures of two common types of sleeve bearings have been investigated and the results compared with theoretical predictions.
