  • the moment bearing is constructed with two bearing rolls. Each of these bearing rolls will have an inner bearing ring and an outer bearing ring. In general, it is desired to have a certain distance between the two bearing rolls and a moment bearing may be asymmetric. Therefore, the gravitational plane might not be arranged at the middle of the moment bearing. Seeing that the bearing lifting tool of the system has a flange which is arranged with holes along the circle, it is possible to provide such holes with a positioning matching the existing holes in the inner ring of a moment bearing.
