<p>This encoder washer comprises a magnetic body (24) and is adapted to be mounted on a rotatable ring of a bearing assembly in a position where a surface (26) of the magnetic body defines an air gap with a sensor of the bearing assembly. The surface (26) of the magnetic body is provided with one groove (265) defining two edges (266, 268) with this surface, wherein these two edges are located either between two lateral edges (262, 264) of the magnetic body (24) or between a radial inner edge and a radial outer edge of the magnetic body. The groove (265) has a rectangular cross section. A first distance (d1) measured between a first edge (266) of the groove (265) and an adjacent edge of the magnetic body, in a direction parallel to the bottom surface (265a) of the groove, is larger than or equal to 0,5 millimeters. A second distance (d2) measured between a second edge (268) of the groove and an adjacent edge (264) of the magnetic body, is larger than or equal to 0,5 mm. The width (W25) of the groove, measured between its two edges (266, 268), is larger than or equal to 0,5 mm and smaller than or equal to a minimum value selected amongst 0,75 × W24, where W24 is the total width of the magnetic body (24), and W24 minus 1 mm. The depth (d265) of the groove, measured between one of its edges (266, 268) and its bottom surface (265a), is larger than or equal to a minimum value selected amongst 0,3 mm and the maximum depth of the magnetic body.</p> |
