圆柱滚子轴承

1、圆柱滚子轴承产品名称圆柱滚子轴承产品型号NU2236NJ1040等等行业应用圆柱滚子轴承主要用于电机、机床、石油、轧机装卸搬运机械和各类产业机械。产品特点圆柱滚子轴承属分离型轴承，安装与拆卸非常方便。圆柱滚子轴承分为单列、双列和四列。 根据轴承装用滚动体的列数不同，圆柱滚子轴 承可分为单列、双列和多列圆柱滚子轴承。其中应 用较多的是有保持架的单列圆柱滚子轴承。此外，还有单列或双列满装滚子等其它结构的圆柱滚子轴承。 单列圆柱滚子轴承根据套圈挡边的不同分为N型、NU型、NJ型、NF型和NUP型等。圆柱滚子轴承承受的径向负荷能力大，根据套圈挡边的结构也可承受一定的单向或双向轴向负荷。 NN型和NNU

2、型双列圆柱滚子轴承结构紧凑，刚性强，承载能力大，受载荷后变形小，大多用于机床主轴的支承。FC、FCD、FCDP型四列圆柱滚子轴承可承受较大的径向载荷，多用于轧机等重型机械上。 圆柱滚子轴承：可在高速运行状态承受重的径向负荷，单列EC型设计的圆柱滚子轴承具优化内部曲线，可提高轴承的径向和轴向负荷能力，同时提高对角度和对准误差的调节能力及改善润滑情况，省略了保持架的满滚子轴承可具有最多数目的滚子。适用于非常重负荷和中等速度的工况。 各项参数 N设计内圈有两个整体式法兰，外圈不带法兰。轴相对于轴承座的轴向位移可在两个方向上在轴承内承受。因此，这些轴承用作非定位端轴承。NU设计NU设计的轴承外圈有两个

3、整体式法兰，内圈不带法兰。轴相对于轴承座的轴向位移可在两个方向上在轴承内承受。因此，这些轴承用作非定位端轴承。由于制造和维护上的原因，以图纸号表示的NU设计的大型轴承的两个外圈法兰不一定是整体式的，而会采用松配合法兰圈的形式。NJ设计外圈有两个整体式法兰，内圈有一个整体式法兰。因此，这些轴承适合轴在一个方向上的轴向定位.NUP设计外圈有两个整体式法兰，内圈有一个整体式法兰和一个松配合法兰圈形式的非整体式法兰。这些轴承可用作定位端轴承，即可提供轴在两个方向上的轴向定位.轴承型号 Designation外型尺寸Principal Dimension额定负荷(kN)Basic Load Rating
