Improvements in or relating to plain bearings or the like

Abstract

Abstract 657,080. Bearings. GLACIER METAL CO., Ltd., and TAIT, W. H. Jan. 11, 1949, No. 743. [Class 12 (i)] [Also in Groups VIII and XXII] A plain bearing comprises poly-tetra-fluoroethylene incorporated in a metallic structure. The metallic structure may be formed of a soft metal such as silver, capable of being sintered at temperatures below 400‹ C., or it may be preformed from wire mesh, gauze or metallic wool, the interstices of which are loaded with powdered synthetic compound which is consolidated into the metallic structure by heat and pressure. Alternatively, the metal at the bearing surface may be formed with small, closely-spaced pits which are filled with synthetic compound. The metallic structure may be produced by sintering a suitable mixture of powders of the synthetic compound and a suitable metal such as silver.
