Abstract
A bearing apparatus includes an outer ring (), an inner ring (), rolling elements () disposed between the two rings, and a seal () 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.
