A press roll intended, together with a press shoe, to cooperate with a counter roll to form a press with long nip for paper or board machines, said press roll comprising two end walls, a jacket, the edge portions of which are secured by an elastic clamping ring to peripheral parts of the end walls, a form-stable clamping ring being screwed to the inner side of the end-wall part to clamp the outwardly expandable elastic clamping ring so that the edge portion of the jacket is clamped firmly against a counter-support member. According to the invention each end wall includes guide means to provide a guided engagement relationship between the form-stable clamping ring and the end-wall part. The guide means includes one axially concentric guide groove in the form-stable clamping ring and an axial, concentric guide flange in the end-wall part for cooperation with the guide groove, the guide groove defining radially externally a radial clamping surface disposed opposite a corresponding clamping surface of the end-wall part for cooperating clamping of the elastic clamping ring.
