A state ring for face-type fluid seals on the back face of which there is formed a support annulus, which annulus serves to take up initial loading against the back face of the stator ring and to compensate for any unevenness in the face or its support, or unbalanced loading. The annulus also serves to overcome an overturning moment which develops in the stator ring of the face-type fluid seal in operation. The dimensions of the annulus are chosen with respect to its material so that initial force transmitted therethrough, when that initial force is not evenly distributed around the annulus, is above the yield point of the material but so that ultimate force transmission through the annulus after distribution of the same is below the yield point of the material.
