Objective: In rolling bearing the contact area between the ball and race plays a vital role for the formation of the lubricant film. Objective of present work is calculation of major and minor axis and further the elliptic contact area developed between the ball & races of the rolling element bearing. Methods/Statistical Analysis: For this bearing 6207 is selected and analytically the contact area is calculated at different load and how the load affects the contact area is analyzed. In addition to analytical method elliptical contact area is also calculated using Artificial Neural Network (ANN). Findings: Using the ANN the error in the calculated contact area is found nearly 1%. So ANN is found to be a successful tool for the prediction of the elliptic contact area. Application/improvement: This eliminates the cumbersome of calculation.
