The method used here consists in testing the interference between balls and rings by moving the inner ring against the outer one. This program [Samper et al. 2001] was written in the Mathematica software. It is based on the Hertz Theory of Contact and the kinematics model of the parameterized ball bearing. The elastic clearance domain in figure 4 is defined for the static limit (4200 MPa).

Those results...
