The present invention provides a rolling bearing device equipped with an IC tag. When the IC tag is attached to the device, the main body or antenna of the IC tag is not easily susceptible to vibration or external force. Especially, even when the attachment is made while exerting a preload on the device, the main body of the IC tag is free from deformation. Further, even when the device is used in an environment where the device is contacted with a lubricant oil or even when the preload must be maintained, the device can surely perform the function of transmitting and receiving information in a stable manner for a long time. In the tapered roller bearing device (5), rolling elements (4) comprising tapered rollers are rotatably retained by a retainer (3) between an outer race (1) and an inner race (2). The outer end metal surface portions of the inner race (2) and the outer race (1) have holes (6) and (7), respectively, in which the IC tag (8) capable of non-contact communication is attached through a shock-absorbing body (9) made of an elastic rubber material. Even when the surface of the outer race (1) or inner race (2) is a surface for receiving a preload, the strain, vibration or impact caused by external force and exerted on the surface is absorbed in the shock-absorbing body (9) made of an elastic rubber material. |
