Abstract:
Provided is a bearing with a sensor, which has a built-in electric power generating function, and has a simple configuration. The bearing (1) is provided with an outer race (2), a plurality of rolling elements (4), an inner race (3), a retainer (5), seal members (6, 7), a sensor (8), a transmitting unit (9), and an electricity generating unit (10). The sensor (8) is situated in the seal member (7), and detects state information of the bearing (1). The transmitting unit (9) transmits the state information detected by the sensor (8) to the outside. The electricity generating unit (10) is disposed in such a way as to face a bearing space sandwiched between the outer race (2) and the inner race (3), and generates electric power to be fed to the sensor (8) and the transmitting unit (9). The electricity generating unit (10) includes an element which converts stress into an electromotive force.
