Structure And Characteristics Of Cylindrical Roller Bearings
Aug 21, 2018

The cylindrical roller is in line contact with the raceway, and the radial load capacity is large, which is applicable to FB090 bronze bushing loading load and impact load, and also for high-speed rotation.

 

The n-type and NU type can be moved to the axial direction, and can adapt to agricultural machinery bearing the change of the relative position of the shaft and the shell caused by thermal expansion or installation error, which is suitable for the free end bearing.

 

NJ type and NF type can withstand a certain degree of one-way axial load, NH type and NUP variable oil cylinder copper sleeve can withstand a certain degree of biaxial load. Inner ring or outer ring can be separated for easy mounting.


NNU type and NN radial load have strong rigidity, mostly used in machine tool spindle.

FC.FCD.FCDP type can withstand large radial load, mainly for rolling mill roll.

These kinds of bearings are mainly used for medium and large electric motors, generators, internal combustion engines, combustion turbine, machine tool spindle, speed reducer, loading and unloading machinery, all kinds of industrial machinery.

Single row cylindrical roller bearing

The NU type and N type allow the axial movement of the shaft relative to the shell in a certain range, so it is suitable for free end bearing.

NJ and NF can be subjected to a certain degree of one-way axial load.

NUP and NFP can be subjected to a certain degree of axial movement in two directions, so it is suitable for free end bearing.

 

Double row cylindrical roller bearing

Two types of cylindrical roller bearings are divided into cylindrical holes and conical holes.

In addition, there are oil holes and oil groove bearings.

This type of bearing is mostly used for machine tool spindle, but it can also be used for other occasions.

 

Four row cylindrical roller bearings

Four row cylindrical roller bearings can withstand a large radial load and impact load, high machining precision and suitable for high speed. It is mostly used in rolling mill roll, but it can also be used for other occasions.
