This document contains summaries of chapters from a textbook on journal bearings. Chapter 6 discusses the Reynolds equation used to model journal bearings and its simplification for long bearings. It also covers pressure waves, load capacity, friction, and practical boundary conditions for long journal bearings. Chapter 7 summarizes analysis of short journal bearings, including flow in the axial direction and bearing stiffness. Chapter 8 discusses design charts and considerations for finite-length journal bearings, including film temperature and experimental design curves. Chapter 9 introduces applications of journal bearings like hydrodynamic whirl and different bearing geometries.
