圆柱滚子轴承概述
单列式
式圆柱滚子轴承是在几个不同的设计制造的，其主要区别在凸缘的结构之中。 最流行的是NU，N，NJ和NUP设计。 圆柱滚子轴承可承受重径向载荷和高转速。 一些不同的晶格结构肋骨也可以承受单向OT双向轴向负荷。 NN和NNU双列圆柱滚子轴承具有低截面，高承载能力，高刚度，因此它主要是在机床主轴看台上使用。 FC，FCD，FCDP型四列径向载荷容量大圆柱滚子轴承，主要是在轧机，重型machiner应用


双列式
双列圆柱滚子轴承
这种类型的轴承是可分离的。 作为其辊线性成与内圈和用较少系数外圈接触，这些轴承径向载荷非常良好的容量，适用于电动电机，汽车，传动轴，齿轮轴等。 双列圆柱滚子轴承善于机床主轴的主轴。
四大行类型
四列圆柱滚子轴承
四列圆柱滚子轴承可携带更重的径向负荷和冲击载荷。 它们具有较高的精度，并且可以在其中具有高转速运行设备施用。 磨滚道和滚子的表面后内圈上辊颈压同时，也有利于轧制精度的提高和安装轴承的游隙的自由调节。 这些轴承主要施加到工作辊与轧机的支承辊和其他一些情况下。
FC：双外圈，单内圈，和内不带法兰。
FCD：双外圈，双内圈，和不带法兰的内圈。
FCDP：双外圈，只有中间法兰，但宽松罗纹，双内圈，内圈不带法兰。

Cylindrical Roller Bearing
Jinan Hongda Bearing mainly manufacture and supply cylindrical roller bearings
Main Types of Cylindrical Roller Bearing
1. single row cylindrical roller bearings, caged, mainly of the NU, NJ, NUP and N designs
2. double row cylindrical roller bearings, caged, mainly of the NNU and NN designs
3. multi-row cylindrical roller bearings, caged (four row&six row)
4. single row full complement cylindrical roller bearings, mainly of the NCF and NJG designs
5. double row full complement cylindrical roller bearings, mainly of the NNF NNCF design
6. multi-row full complement cylindrical roller bearings, with four or eight rows of rollers
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.
