The contact angle is shown for a nominal contact angle of 40°. As for typical axially loaded ball screws, both the load level for all balls and the contact angles of inner and outer race are almost equal along the axial position.

The extension of the contact ellipsis is shown with the dotted lines. The contact angle corresponding to the shoulder is shown as dashed straight line at the top, so the shoulder is high enough in this case.
