Abstract
The bearing (10) according to the invention includes an outer ring (12), with a shape generally of revolution around an axis (X), an inner ring (14), with a shape generally of revolution around the axis (X), positioned coaxially to the outer ring (12), and rolling elements (16), for example balls, positioned radially between the inner ring (14) and the outer ring (12). The rolling elements (16) are at least partially in direct contact with at least one of the inner (14) and outer (12) rings. The ring (12, 14) at least partially in direct contact with the rolling elements (16) is made with a base of a powder of a sintered material.

A bearing (10), including:
- an outer ring (12), with a shape generally of revolution around an axis (X),
- an inner ring (14), with a shape generally of revolution around the axis (X), positioned coaxially to the outer ring (12),
- rolling elements (16), for example balls, positioned radially between the inner ring (14) and the outer ring (12),
- wherein the rolling elements (16) are at least partially in direct contact with at least one of the inner (14) and outer (12) rings, and wherein
- at least one of the rings (12, 14) at least partially in direct contact with the rolling elements (16) is made with a base of a powder of a sintered material.
A mechanical device (18) having a part (20) rotatable around a pivot link (22) comprising:
- at least one bearing (10) having;
- an outer ring (12), with a shape generally of revolution around an axis (X),
- an inner ring (14), with a shape generally of revolution around the axis (X), positioned coaxially to the outer ring (12),
- rolling elements (16), for example balls, positioned radially between the inner ring (14) and the outer ring (12), wherein the rolling elements (16) are at least partially in direct contact with at least one of the inner (14) and outer (12) rings, wherein
- at least one of the rings (12, 14) at least partially in direct contact with the rolling elements (16) is made with a base of a powder of a sintered material, and wherein
- the mechanical device (18) has a structure involving the appearance of a surface fatigue phenomenon on at least one of the outer (12) or inner (14) rings of the bearing (10), at the interface between the outer (12) or inner (14) ring and the rolling elements (16).
