A combined axial and radial thrust bearing device for a rotary shaft composed of two components, each of which comprises an annular ring fixed to the shaft and an annular ring supported free of the shaft both of which rings engage each other through bearing means. Between the two opposing free annular rings is provided a member which is adapted to exert internal pressure on the annular rings in an axial direction to minimize play between the two components. The member is adapted to be actuated by a pressure fluid in such a manner that the internal pressure exerted on the annular rings is reduced in response to an increase in pressure in an axial direction exerted on the shaft externally of the bearing.
