A tidal flow turbine system has a rotor and turbine blades attached at a fixed attitude with respect to the rotor and extending outwardly from the rotor. The stagger angle of the blades, tip speed ratio, or other blade parameters is such that over the in-service operational speed range of the turbine, over a lower range of rotational or tidal flow speeds, increased speed results in increased axial loading on the turbine, but at higher speed range above a predetermined threshold, axial loading on the turbine does not increase.

A revolution speed of balls 8, 8 constituting the outer side row is sensed by a revolution speed sensor 24. Also, a rotation speed of a hub 1a is sensed by a rotation speed sensor 25. A speed ratio as a ratio between a revolution speed and the rotation speed is calculated based on a sensed signal of both sensors 24, 25. When the axial load is changed and then the contact angles of the balls 8, 8 are changed, the revolution speed is changed and in turn the speed ratio is changed. Therefore, the axial load is calculated based on a change of the speed ratio.

Accordingly, the configurations that can be manufactured at a low cost and is able to sense the axial load applied between the hub 1a and the outer ring 4a can be realized.
