On the Laws of Lubrication of Journal Bearings

This paper deals with the physics of lubrication. The principal purpose is to set up certain general relations which may be taken as a guide in the planning and interpretation of experiments to secure data for design. Readers interested only in results available for immediate use are referred to the discussion of the Ideal Bearing in Section V. That part of the paper is intended merely as an illustration of the way in which the foregoing general relations may be applied to particular cases, but the results are doubtless applicable as a first approximation to bearings of whatever type.
