<p><P>PROBLEM TO BE SOLVED: To provide a magnetized pulsar ring that fully enhances magnetic flux density with respect to a magnetometric sensor, and to provide a rolling bearing device with sensor that uses the ring. <P>SOLUTION: The magnetized pulsar ring 11s includes a ring-shaped magnet 12, and a support member 20 having a flange part 22. The ring-shaped magnet 12 includes a connecting surface 12a in contact with one end face 22a of the flange part 22 in a radial direction range K2 that includes a range corresponding to the range which is to be detected K1, in which a magnetometric sensor S detects a change of magnetic poles, and is fixed to the flange part 22 by magnetic attraction by own magnetic force, by contacting the connection surface 12a with the end face 22a. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
