PROBLEM TO BE SOLVED: To provide a rolling bearing device which does not require a special place for attaching a sensor and has interchangeability with convensional bearings. SOLUTION: A recess 8 is formed at a part of the outer ring 2 of a rolling bearing to attach a sensor 9. The sensor 9 is provided with a detector 10 detecting an acceleration, temperature, etc., and a controller 12 actuating a transmitter 11 on the basis of the detected signal. An electric source 13 supplying electric power to the sensor 9 is provided in a hollow 14 of a housing H to which the outer ring 2 is fixedly fitted. And, a receiver 19 is provided to receive radiowaves R transmitted from the transmitter 11 at a detached position. |
