BEARING ELEMENT Russian patent published in 2008 - IPC F16C33/20 C10M149/18 C08L79/08 

FIELD: engines and pumps.

SUBSTANCE: invention relates to a bearing element with a metal thrust body covered with a layer of bearing metal above which laid is a polymer layer, composed of polyamidimide resin, molybdenum disulfide (MoS₂) and graphite. The bearing element is made up of a metal thrust body, a layer of metal laid onto the said metal body, a polymer layer laid on over the metal layer and, if necessary, some other layers to be laid in between the metal and polymer layers. The polymer layer includes polyamidimide resin, molybdenum disulfide (MoS₂) and graphite. Here, note that the content of polyamidimide resin is selected from the range with the lower limit of 23.08 percent by weight and the upper limit of 35.78 percent by weight, that of MoS₂ is selected from the range with the lower limit of 40.37 percent by weight and upper limit of 48.08 percent by weight, while the graphite content is selected from the range with the lower limits of 23.85 percent by weight and upper limit of 28.85 percent by weight.

EFFECT: higher wear resistance, antirust protection, ruling out friction-caused micro welding.
