Self-lubricating sintered bearing mfr.

摘要

Self-lubricating antimony bronze bearing including 3 disperse phases harder than the matrix comprises 1.5-4% Sb, 5-10% Sn, with Sn/Sb = 1.3-3.5, balance Cu and impurities and opt. other additive elements. - The phases each consist of a diffusion ring continuous with the matrix surrounding a micropore and having a ternary intermetallic compsn. (Cu, Sn, Sb). The diffusion rings have a hardness Hv of at least 200.
