Since the future aircraft engine calculation work temperature is very high bearing maintenance technology existing problems and solutions, to this kind of work under the condition of the bearings of effective lubrication, of the present various kinds of synthetic lubricants are powerless. As is known to all, the temperature is more than liquid lubricant allowed by the limit, can use contains all the different chemical element of oxide, sulfide and fluoride, high temperature resistant, performance and stability of solid compounds.

Many ordinary solid lubricant became effective lubricant, is due to its lattice is easy to be disconnected, such as graphite and mos2 is such. Eccentric bearing and overall eccentric bearing the size of table in air, graphite lubricant to the temperature limit range depends on its oxidation degree. By adding antioxidants or metal salt, imperial roller bearing specifications and customized arrangements can obviously improve the oxidation limit, so as to improve the bearing surface graphite membrane performance.

SKF has shown that si3n4 with contain high temperature lubricating additive of graphite, the surface can form a layer of friction resistance chemical film, it can reduce the azotized silicon of the friction coefficient, make to minimize friction temperature rise.
SKF also to other some can withstand 550 ℃ high temperature above the solid lubricants are studied, their thermal stability than graphite and mos2 is good. Roller bearing the size of parameter table at present, the company is in a MRC bearing lamps (PbO), a eutectic fluoride barium (CaF/BaF) mixture and a cesium molybdenum compounds for the test.
