,""注意到一些泵的止推轴承是双列角接触，通常很多都是成对单列角接触，请问在哪些情况下会选择双列以及双列和单列的具体区别"

,""双列的可以节省轴向空间"

,""设计上基本上和单列的一样"

,""双列的要比两个单列组合在一起的动载荷和静载荷要小些，在余量小的情况下慎用双列的，双列的的轴向长度要小些可以节省一些轴向空间双列的安装拆卸方便不会有误安装双列的规格比单列少些没有太大规格的双列的"

,""双列的规格也可以做到很大的SKF内径做到281mm"

,""成对使用的角接触球轴承，不是简单的两个轴承放一起他们在出厂的时候进行调整配对使用后的游隙被调整相当高的精度同时价格不便宜双列的价格就会相对便宜因为没有单独调整这一道工序除了价格还有一点成对使用时可以任意组合方向比如背对背面对面串联双列的的不行就一种方向没有选还有由于结构的不同他们对于角度的允许误差也是是不同的"
