    摘要: A self-lubricating bearing material is described, as well as a plain bearing of such a bearing material, the performance of which, under lubricant-free conditions, is so markedly improved that pv values of up to 6 MPa/m/s are achieved in an average load and speed range. The self-lubricating bearing material comprises a PTFE-containing polymer matrix with fillers comprising PbO and at least one metal fluoride. The PbO content is from 15-55 vol. % and the metal fluoride content is from 0.1-14 vol. %. Preferred metal fluorides are CaF.sub.2, PbF.sub.2 and MgF.sub.2. The addition of further fillers such as hard materials, pigments or fibrous material is possible. The proportion of further additives may amount to up to 40 vol. % of the PbO/metal fluoride fillers.
