The inner ring moves both vertically and horizontally at a given step in a certain range, and the position relation (contact, separation, interference) between the inner raceway and each roller at the bottom of the bearing is obtained in different positions, and the number and position angle of rollers which contact with the inner raceway are obtained.

Pole figure is scanned by measuring at a fixed 2th position angle (crystal orientation), a complete scan (spins the sample about its normal) can be performed at each specific tilt angle (Ps).Pole figure measurement is considered as an important process needs to be undertaken to get a successful characterization of the sample [9].
