Paragraph 2 enabled us to calculate the Hertz pressure as a function of the normal load Q exerted on the ball. It details the distribution of forces on the balls in a bearing subjected to any combined loading. It presents the exact method for calculating the load exerted on each ball in a bearing.

The approximate method is much better known, as it is presented in bearing catalogs. It uses the notion of...
