Textured particle trap bearing, characterized; - because the bearing comprises a cage formed by an upper ring (1) joined by spokes (3) to the lower ring (2) where the surface of the upper face of said lower ring (2) presents a curvature (3), - and because the functional tracks present a texture formed by some dimples (12) distributed homogeneously in all directions of the contact surface, where the diameter and depth of the dimples (12) is subject to an aspect ratio of diameter divided by height with values ranging between 0.1 and 0.15, where the density of dimples (12) is constant over the entire surface and ensures, according to Hertz's contact theory, that there is always a minimum number of dimples within the contact with the counterpart and where the transition between the surface (7) and the dimple (12) is rounded with a predefined radius (14) to avoid stress concentration.
