<p><P>PROBLEM TO BE SOLVED: To realize structure that can accurately detect a plurality of states of a double row rolling bearing 1 such as vibration and temperature in addition to rotating speed. <P>SOLUTION: A detected ring 10c is directly fitted and fixed to the outer peripheral surface of a hub 22 constituting an inner ring having double rows of inner ring raceway tracks 6, 6 on the outer peripheral surface together with an inner ring element 18. A sensor unit 31 is supported to an outer ring 5 provided around the hub 22. Sensors such as a temperature sensor and an acceleration sensor for measuring vibration in addition to a rotation detecting sensor are held to the sensor unit 31. <P>COPYRIGHT: (C)2004,JPO</p> |
