圆柱滚子轴承的概述
单个行类型
单列圆柱滚子轴承主要差异在法兰配置中的几个不同的设计，制造。最受欢迎的是怒江、 N，NJ 和 NUP 的设计。圆柱滚子轴承可以容纳重的径向载荷和高转速。一些具有不同结构的肋骨也可以承担单程 ot 双向轴向负荷。神经网络和 NNU 双列圆柱滚子轴承有低断面、高承载能力和刚度高，因此它主要用于机床主轴看台。FC、 FCD、 FCDP 四排圆柱滚子轴承的径向载荷，大容量主要应用于轧机和重型机械

双行类型
双列圆柱滚子轴承这种类型的轴承是可分离的。作为它们的滚子线性接触的内圈和外圈带系数较低，这些轴承有很好的能力的径向负荷，适用于电机、汽车、传动轴、齿轮轴等。双列圆柱滚子轴承都擅长的机床主轴主轴。

四行类型
四列圆柱滚子轴承四列圆柱滚子轴承可以携带多更重的径向载荷和冲击载荷。他们有较高的精度，可以应用于高转速运行的设备。它在同一时间内圈滚子脖子上按下后磨滚子与滚道表面，有利于提高轧制精度与安装轴承游隙的自由调整。这些轴承主要应用于工作辊和支承辊轧机和某些其他情况。 FC: 双外圈、单一的内圈和内无凸缘。 FCD: 双外圈内, 圈和内的圈法兰无一倍。 FCDP: 双外圈，仅有中心法兰，但与松肋骨，双内圈内无凸缘。

Overview of Cylindrical Roller Bearing
Single row Type
Single row cylindrical roller bearings are manufactured in several different designs, the main difference being in the configuration of the flanges. The most popular are the NU, N, NJ and NUP designs. Cylindrical roller bearings can accommodate heavy radial loads and high speeds. Some with different strcuture of ribs can also bear one way ot two way axial load. NN and NNU double row cylindrical roller bearings have a low cross section, high load carrying capacity and high stiffness, therefore it is mostly used in machine tool spindle stands. FC, FCD, FCDP four row cylindrical roller bearings with large capacity of radial load, mostly applied in rolling mill and heavy machiner

Double Row Type
Double-row Cylindrical Roller Bearing This type of bearings is separable. As their rollers linearly come into contact with inner ring and outer ring with less coefficient, these bearings have very good capacity of radial load, suitable for electric motors, automobiles, transmission shafts, gear shafts and so on. Double row cylindrical roller bearings are good at the spindles of spindles of machine tools.

Four Row Type
Four-row cylindrical roller bearings Four row cylindrical roller bearings can carry much heavier radial load and shock load. They have higher precision and can be applied in the equipment which runs with high rotational speed. Grinding the surface of raceway and roller at same time after the inner ring is pressed on roller neck, it favors the improvement of rolling precision and the free adjustment of mounting clearance of bearings. These bearings are mostly applied to the working roller and backup roller of rolling mills and some other cases. FC: double outer rings, single inner ring, and inner without flange. FCD: double outer rings, double inner rings, and inner ring without flange. FCDP: double outer rings, only have center flange, but with loose rib, double inner ring, inner without flange.
