A pressing roll for the production or treatment of web or band shaped materials, particularly fiber webs or bands, with the roll jacket of the pressing roll being rotatably arranged about a carrier and journalled via a pressing device, with the pressing device having at least one support element that includes at least one supporting pressing element acting in the direction of a pressing area and being supported on the carrier, with the at least one support element being displaceable in the circumferential direction as well as being radially movable relative to the pressing element and which, in the circumferential direction, is supported on a spacer on a limit stop, attached to the carrier, via at least one spacer, the spacer permitting a radial movement relative to the limit stop in the transition between an unloaded and a loaded condition of the support element at a substantially fixed support point of the spacer at the limit stop or at the support element, with a low friction support, in the circumferential direction, being assured at the limit stops particularly during the loaded condition, via a spacer that permits at least a minimal radial movement during the loaded condition of the support element at a constant support point of the spacer at the limit stop and at the support element.
