<P>PROBLEM TO BE SOLVED: To provide a bearing device equipped with an IC tag in which any distortion is avoided in an IC tag body by preventing the IC tag body and an antenna from being easily susceptible to any vibration or external force when the IC tag is mounted to the bearing device, especially when the IC tag is mounted to the bearing device with a precompression given to the bearing device, the IC tag body is also available in an environment in contact with a lubricating oil, and information transmission and reception functions can be surely exerted stably over a long term even when the precompression need be maintained. <P>SOLUTION: In a conical roller bearing 5 with a roller element 4 consisting of a conical roller maintained to be freely rotatable between an outer ring 1 and an inner ring 2 with a retainer 3, the outer edge metal surfaces of the inner ring 2 and the outer ring 1 have holes 6, 7 respectively. In these holes 6, 7, the IC tag 8 of non-contact communication type is mounted via a buffer body 9 consisting of a rubber-like elastic material. If the outer ring 1 or the inner ring 2 is a precompression surface, and these surfaces are applied with the external force, the distortion, shock and vibration by the external forces are absorbed by the buffer body 9 of the rubber-like elastic material. <P>COPYRIGHT: (C)2013,JPO&INPIT |
