该产品由套圈（内圈+外圈）、滚子、保持架、密封圈组成，不同的是滚动体大小、长度有区别，超大型三排滚子结构通常用长滚子甚至双排滚子。因直径和滚动体都比较大，所以能承受巨大的轴向力、径向力和倾覆力矩，对工艺设计、设备尺寸及精度，工人加工水平的要求比较高。广泛应用全回转浮式起重机，大型船用起重机等机械上使用。
该产品主要结构和普通的三排圆柱滚子结构一样，有内齿式、外齿式、无齿式三种结构。
Split three-row roller slewing bearings are engineered to manage the substantial demands of heavy-duty marine applications. Unlike conventional bearings, these feature segmented inner and ...
The integrated three-row roller slewing bearings are 设计ed to handle the significant axial, radial, and overturning loads typical in large marine equipment like full-rotation floating cranes and heavy-duty ship cranes.
