Abstract
A radially directed pressure applying member is disposed between a nonrotative inner shaft and a rotative outer shell encircling the nonrotative inner shaft, which comprises a controlled deflection roll assembly. The pressure applying member includes a fluid filled toroidal shaped flexible membrane disposed on the outer end of a hydrostatic piston arranged radially within the nonrotative shaft. The toroidal shaped membrane acts as a bearing and a fluid cushion on the inner surface of the outer shell to uniformly support the shell and to avoid deflections caused by external loads or to deflect the shell in a predetermined way.
