洪基粉末冶金厂经过一年多的反复试验,最近研制成功托滚粉末冶金球面含油轴承。托滚粉末冶金球面含油轴承是普通滚动轴承的新型替代产品,主要特点有:一是具有较高的耐磨性,长时间使用无需加油;二是粉末冶金材料热涨冷缩系数极小,含油轴承在较高温度环境下仍能正常工作;三是结构性能独特,无论在何种环境与条件下使 Hongji Powder Metallurgy After more than a year of trial and error, the recent successful development of Rolling powder metallurgy spherical oil bearing. Rolling powder metallurgy spherical oil-bearing is a new alternative to ordinary rolling bearing, the main features are: First, have a high wear resistance, long time without using fuel; Second, the powder metallurgy material thermal expansion and contraction coefficient is very small, oil-bearing In the high temperature environment can still work normally; Third, the unique structure and performance, no matter under what circumstances and conditions
