MAGNETIZED PULSAR RING AND ROLLING BEARING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a magnetized pulsar ring capable of preventing breakage due to temperature change and to provide a rolling bearing device having the magnetized pulsar ring.

SOLUTION: A magnetized pulsar ring 11 comprises: an annular metal supporting member 20 attached to a rotor so as to be rotatable integrally with the rotor; and an annular magnet member 12 which is fixed to the supporting member 20 and in which multiple magnetic poles are arrayed in a circumferential direction. The magnet member 12 is formed of magnet material containing magnetic powder, binder and glass fiber.
