摘　　要：空心圆柱滚子轴承是一种新型滚动轴承,其结构特点是滚动体的空心度大于50％,无保持架,满装滚子和滚动体始终受有预负荷。它具有高刚度、高回转精度和高极限转速等特性,特别适用于机床主轴轴承。空心圆柱滚子轴承的主要失效形式是磨损和滚动体的弯曲疲劳断裂。The hollow cylindrical roller (HCR) bearing is a new type of rolling bearings. Its structural characteristics include: the hollowness of roller is higher than 50%, the bearing is completed with rollers without bearing cage, and the rollers are always in the preloaded state. Therefore, the HCR bearing shows a series of high performance, such as high stiffness, high rotationary accuracy, high limited speed etc. It is specially suitable for application on the spindle of precision machine tools. It's main failure models are wear and fluxural fatigue fracture of rollers.
