ABSTRACT:
A web guide roller assembly for a printing machine utilizes a cylindrical roller support body and a concentric hollow roller body. An annular space between the support body and the roller body is filled with a pressure medium so that the roller body floats on the support body. Suitable end seals are utilized to prevent escape of the pressure medium.
