Evaluation of an internally spring preloaded four contact ...

In a conventional spindle bearing the rotation causes a centrifugal force F c on the balls and the inner ring which results in a radial expansion of the inner ring ( Updelta x_{rad} ) and a movement of the balls. This leads to changing contact angles resulting in an axial displacement of the inner ring ( Updelta x_{ax} ).The changed contact angles cause a …
