A rotary vane steering gear driven by a rotary vane hydraulic actuator, having a body confining an internal hydraulic space in the shape of toroid with a rotation axis (X-X). The body is divided by a plane (A-A) perpendicular to the rotation axis and in case of a circular torus shaped hydraulic space passing through the center point of the circle delimiting the space, the plane divides the space into a movable part (rotor 1.1) and a stationary part (stator 1.2). Both parts are bound by two thrust rings, that are fastened concentrically on the radially opposite sides of the hydraulic space, each to the respective edge of one body part and in radial overlap with the other body part, to create two concentric slewing bearings.
