<P>PROBLEM TO BE SOLVED: To provide a pulsar ring capable of accurately detecting a rotational frequency, or the like, of a rotation part, such as, a wheel by surely bonding a pulsar, comprising a synthetic resin on an accurate position on the outer periphery of a cylindrical metal core, and to provide a manufacturing method for the ring, and a bearing device for an axle using the pulsar ring. <P>SOLUTION: This pulsar ring 20 mounted on the bearing device, for detecting rotation of the bearing device, is formed of the cylindrical metal core 21, whose outer periphery is formed on a tilted surface; and the cylindrical pulsar 25 comprising the synthetic resin, whose inner periphery is formed on a tilted surface corresponding to the tilted surface of the metal core 21, and is fitted and bonded to the outer periphery of the metal core 21. <P>COPYRIGHT: (C)2010,JPO&INPIT |
