A heat-resistant bearing material may include an austenitic iron matrix alloy having a proportion of sulphur sufficient to achieve a solid lubricating action on bearing surfaces of the heat-resistant bearing material. The iron matrix alloy may have a proportion of carbides to achieve a reduction of wear on bearing surfaces of the heat-resistant bearing material and a proportion of 1 to 6 percentage by weight of at least one alloying element including cobalt, niobium, rhenium, tantalum, vanadium, tungsten, hafnium, yttrium and zirconium. The iron matrix alloy may also include the following alloying elements: carbon, chromium, manganese, silicon, nickel, molybdenum, niobium, tungsten, sulphur, copper, nitrogen and iron.
