Abstract
In a rotary machine bearing including an inner ring, an outer ring, and rolling elements between them, one of the inner and outer rings includes first and second half-rings suitable for being clamped in the axial direction between a thrust member and a first pre-loading system exerting a first predetermined axial force, and a second pre-loading system is provided that is inserted in the axial direction between the first and second half-rings and that exerts a second predetermined axial force less than the first predetermined axial force.
