Wear ring and wear ring arrangement

A wear ring for guidance of two machine components which are arranged movably relative to one another along/around a movement axis, the wear ring being formed in one piece from a plastic or a reinforced plastic material and which is slit wherein it has two free ends, wherein the wear ring has a radial outer side, a radial inner side and two side flanks, wherein the wear ring has a cross-sectional width W, which, with respect to a wear ring's central axis, at least sectionally increases in a radial direction towards the radial inner side thereof and wherein the wear ring has one or more recesses formed on the radial outer side and/or on the radial inner side, wherein the recesses of the radial outer side and the recesses of the radial inner side are spaced from one another in the direction of the central axis of the wear ring and wherein the recesses of each side of the wear ring are arranged spaced apart from one another in the circumferential direction of the wear ring, wherein the one or more recesses are not sharing an edge to either of the two side flanks but are disposed at least a distance apart from the two side flanks wherein a surface portion of the radial inner side or the radial outer side is disposed between the one or more recesses and the two side flanks.
