滚动轴承是一种高度标准化的机械零件，有着多种尺寸规格和精度等级的系列型号。可以在相当大的范围内满足各种机械对轴承的要求。由于滚动轴承的维护十分简便，因此得到了非常广泛的应用。滚动轴承结构的最大特征是，在有相对运动的两个套圈之间放置有滚动体，因此，滚动轴承 Rolling bearings are highly standardized mechanical parts with a range of sizes and accuracy grades. A wide range of mechanical bearings to meet the requirements. As the maintenance of rolling bearings is very simple, so it has been very widely used. Rolling the most prominent feature of the structure is placed between the two rings with relative movement of the rolling element, therefore, the rolling bearing
