滚动轴承的工作能力与其径向间隙的大小有关。根据多次试验的结果断定,必有一段最有利的径向间隙可使轴承具有最高的寿命。按照现行的标准,同一结构形式和用途的轴承,其径向间隙值仅仅是根据轴承内径尺寸而确定。例如,外径280、250及230毫米,轴颈130、135毫米, Rolling bearing capacity and the size of its radial clearance. According to the results of several tests concluded that there must be some of the most favorable radial clearance can make the bearings with the highest life expectancy. According to the current standards, the same structure and use of bearings, the radial clearance value is only based on the size of the bearing diameter determined. For example, outer diameters 280, 250 and 230 mm, journals 130, 135 mm,
