Gas bearing for use in rolls (1) and rollers having a shaft (2) and a rotating envelope part (3) supported by bearings on the shaft, said bearing comprising an inner part fitted to the shaft (2) and an outer part fitted to the envelope (3), with a clearance (6) between the inner and outer parts, into which clearance a gas used for lubrication is supplied via nozzles (20) or a porous material. The inner part fitted on the outer surface of the shaft of the roll or roller consists of separate detachable sleeves or segments forming an inner ring (127), that the outer part rotating around the inner ring and having a cylindrical inner surface or consisting of cylindrical segments forms an outer ring (125), and that the inner and outer rings are attached via flexible or articulated joints to the shaft and the rotating envelope so that they allow the inner and outer rings to adapt to a common axis of rotation formed by the shaft and the envelope.
