FIELD: mechanical engineering; bearings. ^ SUBSTANCE: proposed bearing contains layer of backing material, porous layer placed on backing layer and bearing extruded material layer applied by impregnation to porous layer and having continuous hardened structure including continuous polytetrafluoroethylene matrix and separate particles of addition material. Bearing material layer has part of porous layer. Claimed in invention is bearing plastic material which includes extruded non-baked tape or strap designed for impregnation in porous layer arranged on backing material and including polytetrafluoroethylene matrix and separate particles of addition material. Claimed also is method of producing plastic material of bearing according to which first extruded non-baked tape or strap is made containing polytetrafluoroethylene matrix and separate particles of addition material, and then tape is placed by impregnation in porous layer on backing material and then is baked at temperature high than melting temperature of polytetrafluoroethylene to form continuous hard layer of bearing material. ^ EFFECT: provision of bearing without bulges and featuring improved wear resistance and higher erosion resistance. ^ 38 cl, 1 tbl, 3 ex, 1 tbl |
