Bearing system, bearing system control method, and computer program for controlling bearing system

In order to enable a bearing system in which a plurality of bearings operate simultaneously or in association with each other to achieve an optimal overall performance: this bearing system is equipped with a bearing A and a measurement execution unit A therefor, a bearing B and a measurement execution unit B therefor, and a control unit for controlling the measurement execution unit A and the measurement execution unit B; the control unit transmits an instruction to the measurement execution unit A and measurement execution unit B to enable execution of the performance required of the bearing system; the measurement execution unit A and the measurement execution unit B respectively operate the bearing A and the bearing B under an instructed operation condition; the relation of an operation condition A of the bearing A and an operation condition B of the bearing B to an index, which indicates the operational states of the bearing A and the bearing B when the bearing A and the bearing B are operated under the operation conditions therefor, is measured and saved in advance; and the control unit references the relation and accordingly transmits an instruction to the measurement execution unit A and the measurement execution unit B.
