Abstract
To provide a sensor equipped wheel support bearing assembly, in which a load sensor can be installed compactly in an automotive vehicle, maintaining a high sensitivity while damage and/or malfunction caused by the external environments and/or the electromagnetic noises are avoided, with low manufacturing cost. This bearing assembly includes outer and inner members having respective rolling surfaces and a plurality of rows of rolling elements interposed between those rolling surfaces. A strain sensor unit including a sensor element is fitted to one of the outer and inner members, which is a stationary member, for example, the outer member. A sensor mounting surface of the strain sensor unit fitted with the sensor element has a covering member made of a resin, which is over-molded, or an elastomer bonded by vulcanization, so as to cover the sensor element sealingly.
