Abstract: The invention relates to a wear ring (10) for guidance of two machine components (30, 32) arranged movably relative to one another along/around a movement axis (34), which is formed in one piece from a plastic or a reinforced plastic material and which is slit such that it has two free ends (14). The wear ring (10) has a cross-sectional width W, which at least sectionally, increases in a radial direction towards the rear side of the wear ring (10). The wear ring has one or more recesses (24) formed on its front side (16) and/or on its the rear side (18) for increasing its deformability and thus facilitate mounting thereof in a mounting groove of a machine element (30, 32). The invention further relates to a wear ring arrangement with a wear ring clipped into a mounting groove (54) of one of the machine components (30, 32) of the wear ring arrangement (100).
