摘要

A bearing (1) for supporting a rotating member, for example a wheel (2) of a vehicle, and simultaneously allow detection of the angular velocity of the said rotating member by means of an electromagnetic sensor (21), for example forming part of an anti-lock system of ABS type; characterized by the presence on one (3) of the bearing rings which can be fixed for rotation with the rotating member, of an annular groove (12) which is filled with a paste (13) containing ferromagnetic material. The paste is subsequently shaped into the form of a toothed ring (14) and caused to solidify so as to cause the presence within the interior of the groove (12) of a solid ferromagnetic substance defining in succession a plurality of peaks and troughs. <IMAGE>
