As the circumferential position of the rolling elements within the bearing may affect the results, an option to define the position of the first rolling element by means of the angle is available. If a custom angle is desired, it can be entered by using the 
-button.
The selection “First rolling element on load direction” uses the radial displacement for definition of the angle. For pure moment load the angle is set to zero. In most cases this settings leads to the maximum contact stress and the lowest life.
The selection “Load direction between rolling elements” uses the radial displacement for definition of the angle and adds half the pitch angle. For pure moment load the angle is set to zero.
The option is not yet available for track roller calculation with elastic outer ring.
