轧机轴承
FC FCD NU NNU NN NCF NNF(SL)(RS) 四列圆柱滚子轴承和六列圆柱滚子轴承 圆柱滚子轴承的品种范围包括以下各种基本类型：
| – | 带保持架的单列圆柱滚子轴承，主要为NU、NJ、NUP和N设计 |
| – | 带保持架的双列圆柱滚子轴承，主要为NNU和NN设计 |
| – | 带保持架的多列圆柱滚子轴承，和 |
| – | 单列满滚子圆柱滚子轴承，主要为NCF和NJG设计） |
| – | 双列满滚子圆柱滚子轴承主要为NNF设计 |
| – | 多列满滚子圆柱滚子轴承，带四列或八列滚子 |
除标准品种外，圆柱滚子轴承还包括：
| – | 用于轧钢机的开放式或密封式多列圆柱滚子轴承； |
| – | 用于多辊型冷轧机的支承轴承； |
| – | 用于连续冶炼炉的分度滚子组件。 |
四列圆柱滚子轴承和六列圆柱滚子轴承几乎全部用于轧钢机架的轧辊颈、滚筒和轧压机。同其它滚子轴承相比，这些轴承的摩擦低。由于这些轴承通常以过盈配合安装在轧辊颈上，特别适合轧钢速度高的轧钢机应用。 这些轴承的低横截面允许使用同轧辊直径相比相对较大的轧辊颈直径。由于可装入非常多滚子，其径向载荷能力非常高。 多列圆柱滚子轴承只能承受径向载荷。因此，这些轴承同深沟球轴承或角接触球轴承、或径向设计或止推设计的圆锥滚子轴承一起安装，由后者承受轴向载荷。 四列和六列圆锥滚子轴承为分离式设计，即带整体式法兰的轴承圈及滚子和保持架组件可同分离式轴承圈分开安装，或所有轴承部件均可分别安装。这在相当程度上简化了轴承安装、维护和检查。轴承内可承受一定限度的轴相对于轴承座的轴向位移。 四列圆柱滚子轴承带一个圆柱孔，一些尺寸的轴承还可带圆锥孔供应。带圆锥孔的轴承可在安装过程中调整，以得到一定的径向内部游隙或确定的预载荷
