A combination flexible web roller guide assembly and an integral centrifugal pump (fan) functional device located inside the roller's outer surface where an air bearing flexible web support Hydrostatic air film is created upon the roller guide's exterior circular surface. The air bearing film is created when a web is mounted onto the roller's exterior surface with web tension applied and the roller's Outer Tube is rotated by some external means. This results in a web support device that possesses the advantages of roller guides AND air bearings, and none of their disadvantages. A highly reliable mechanical device is obtained simply by the incorporation of centrifugal fan-like vanes and an air path from the atmospheric exterior, to inside the outer tube of the roller into spaces between the vanes, and finally through multiple air ports located on the roller's outer tube surface. Air is pumped with Centrifugal Forces generated by the Roller-Air Pump device being rotated by any external means.
