双列向心对称球面滚子轴承(我国代号53000型)是由内圈、外圈、活动中档圈、两个钢板冲压保持架和双列滚子组成。与双列向心球面滚子轴承(我国代号3000型)比较,53000型轴承之中挡圈是可拆卸的,工作时可做轴向位移,故可补偿轴承在轴向负荷时一列滚子卸载而另一列过载的情况,从而使载荷均匀分布,故能提高轴承的动负荷容量。内圈取消小挡边,有利于滚道磨削,提高精度和光洁度,并有利于锻造工艺的改进,节约原材料,提高材料利用率。滚子无大小头之分,有利于实现自动化加工、测量和安装。保持架采用钢板冲压制造,可以节
Double row centripetal spherical roller bearings (China code 53000 type) is composed of inner ring, outer ring, mid-range gear, two steel stamping cage and double row roller. And double row radial spherical roller bearings (our code-named 3000), 53000-type bearing in the ring is removable, the axial displacement can be done at work, it can compensate for the axial load in a row when the roller unloading The other case of overload, so that the load evenly distributed, it can improve the bearing dynamic load capacity. The inner ring to cancel a small wall, is conducive to raceway grinding, improve accuracy and finish, and is conducive to forging process improvement, saving raw materials, improve material utilization. Roller size of the first division, is conducive to automated processing, measurement and installation. Cages made of steel stamping, you can section
