Abstract: A bearing apparatus has a rolling bearing including an outer ring (11), an inner ring (12), and rolling elements (13) disposed between the two rings, and a temperature sensor (TS) for measuring an internal temperature of the rolling bearing. A wire from the temperature sensor extends to the outside via a through-hole (11d) formed in a component of the bearing apparatus, and hence the temperature sensor can be disposed in a desired position with excellent wiring extension flexibility, thereby enabling a temperature in the desired position of the bearing to be measured. The temperature sensor, which can be configured thin in a small size with flexibility, can therefore be incorporated into whichever portion of the bearing, wherein a high response to temperature detection is attained, and detectability of abnormality in temperature can be improved.

Abstract: A bearing apparatus includes an outer ring (11), an inner ring (12), rolling elements (13) disposed between the two rings, and a seal (15) attached to one of the outer ring and the inner ring and extending toward the other ring. A temperature sensor is fitted to the seal, and hence a temperature of the seal contacting with a rotary wheel can be directly measured. Accordingly, if the temperature measured by the temperature sensor rapidly rises, this implies that some inconvenience might occur, and necessary countermeasures such as immediately stopping an apparatus using the bearing apparatus can be taken before the explicit inconvenience occurs.
