Accordingly, the axial force F exerted on the inner rings 7, 9 can also vary between a minimum value F min and a maximum value F max.
- the minimum value x min for the axial deformation path x and thus the minimum value F_min for the axial force result for a first combination of maximum exhausted tolerances in the axial dimensions.
