An intermediate rotatable member is driven at relatively high speed about a common axis and is concentrically positioned between first and second relatively rotatable members, one of which is bidirectionally driven with respect to the other. Hydrodynamic fluid bearings are carried by the intermediate member on both surfaces thereof and acting on the first and second members, thus even upon cessation of motion, between said first and second members, there is no loss of the hydrodynamic fluid bearings between the first, second and third members.

A vibration-isolating apparatus having orthogonal X, Y, and Z axes is provided for mounting a payload to a base. The payload contains a torque producing device. Torque generated about the X-axis in the payload is communicated to the base through a stiff linkage in the rotational degree of freedom about the X-axis. The apparatus includes first and second support frames, the payload mounted on the first support frame and the second support frame mounted to the base. Gimbal means permit rotation of the payload about the Y and Z axes. Linear dampening means dampen forces between the payload and base communicated linearly along the X, Y and Z axes and rotation dampening means dampen forces between the payload and base communicated rotationally about the Y and Z axes.
