    In this chapter the theory from Chapter 9 will be applied to rolling bearings. The thin layer flow equations are used to describe the tangential and normal flow due to centrifugal forces. The interaction between the various contacts on inner ring and outer ring will be described followed by the effect of the scraping action of the cage on the starved EHL bearing contacts. The chapter is concluded with film thickness measurement results from full bearings. This edition first published 2013
