简介了机车轮对轴承脂的理化性能和技术条件，并着重介绍了其模拟台架评一定、现场试验和应用情况及应用注意事项等，并与美国进口机车胎进行了比较。说明机车轮对轴承脂的使用性能与具有国际先进水平的美国Exxon／k司Ronex．MP、No．2轴承脂相当，并已取代美国脂在ND5型机车上使用。在东风4型机车国产新结构轴承上装车试验，效果良好。
The physical and chemical properties and technical conditions of locomotive wheel bearing grease are introduced. The simulation bench evaluation, field test, application and application precautions are introduced emphatically. The comparison is made with the locomotive tire imported from the United States. Description of the locomotive wheel bearing grease performance with the international advanced level of the United States Exxon / k Secretary Ronex. MP, No. 2 bearing grease, and has replaced the United States fat in ND5 locomotive use. Dongfeng 4 locomotive domestic new structure bearing loading test, the effect is good.
