Product Description



What is a  Cylindrical Roller Bearing?

Cylindrical roller bearing are of high load capacity and can operate at high speeds because they use rollers as their rolling elements. They can therefore be used in applications involving heavy radial and impact loading.


The rollers are cylindrical in shape and crowned at the end in order to reduce the stress concentrations. They are also suitable for applications that require high speed because the rollers are guided by ribs which are either on the outer or inner ring.


More information

With the absence of ribs, either the inner or outer ring will move freely so as to adjust to axial movement hence can be used as free side bearings. This enables them to absorb shaft expansion to a certain extent, relative to the housing position.


NU and NJ type cylindrical roller bearing produce high performance results when used as free side bearings because they possess the required characteristics for that purpose. NF type cylindrical roller bearing also supports the displacement of the axial to a certain extent in both directions and therefore can be used as a free side bearing.


In applications where heavy axial loads have to be supported, cylindrical roller thrust bearings are the most suitable. This is because they are designed to contain shock loads, are stiff and the axial space required is little. They only support axial loads that are acting in a single direction.


Detailed applications

Specifically, our cylindrical roller bearings can be used in industrial transmission, automotive, electric motor, generator sets, elevating machinery, machine tool spindles as well as internal-combustion engines, etc.



These roller bearings can be separated and are easy to mount as well as dismount.

10  Physical Characteristics: 

      1)  Cylindrical roller bearing can be separated by single row,double rows and four rows.

      2)  This kind of bearing can be submitted to high radial load and some axial load.

      3)  The rolling element of cylindrical roller bearing is cylinder,the two ends of the external lines have the corrective slope which can eliminate the contact stress.

      4)  NN and NNU design cylindrical roller bearing have high rigid and apply to machines such as millings.

Q:How much is the working temperature of spherical bearing
A bearing seat with a heat sink or a water-cooled bearing seat can also be adopted!
Q:How to check bearing type mechanical manual
There seems to be no bearing sample in the machine manual
Q:Fixed fc207 bearing seat. Do not use flat pad. Can you use straight nut lock?
3. Increase the degree of force balance between the bolt cap and the connecting piece.So, if not helpless, or recommend a flat pad.
Q:(seat) note bearing bearing bearing lubrication domestic installed outside the sphere?
Two, check the size of relevant parts and finishingThree, installation method of the spherical bearing should be installed according to the bearing structure, with the properties of size and bearing components and pressure should be added directly in a tight fit to ring face, shall not pass through the rolling pressure.
Q:The difference between bearing and bearing seat.
The bearing is used to allow the shaft along the circumference of the supporting shaft and operation, the conventional usage is two or more than two bearing, its role is to make the normal operation of the shaft, and the bearing seat is used to support the bearing, the bearing outer ring is fixed to the inner ring outer ring, just turn, remain motionless, always keep consistent with the direction of transmission (such as motor running direction), and keep the balance.The science of bearing housings is defined as a component that supports a bearing on a cylinder body or base of a turbine. In the conveyor belt machinery industry, there is no lack of bearing seat. Since the bearing seat is so important, then do you know the function of the bearing seat? Today, Xinda tells you about the function of the bearing seat.The bearing block is used to support the bearing. The outer ring of the fixed bearing only rotates the inner ring. The outer ring stays the same, always in accordance with the direction of transmission (for example, the direction of the motor), and keeps balance. Bearing is the concept of bearings and boxes of the aggregate, easy to use, the advantages of the sample can be better coordination, convenient use, less use of manufacturers costs. Shaped and varied, usually a case bearing can be mounted in it.
Q:What are those inside bearings mean?
What kind of bearings do you want to ask? That is the type code of the bearing. For example, the new national standard "0" refers to the type of bearing double row angular contact ball bearings; "1" refers to the self-aligning ball bearing; "2" refers to the spherical roller bearings and thrust roller bearings; "3" refers to the tapered roller bearing; "4" refers to the "5 double row deep groove ball bearings;" refers to the thrust ball bearing; "6" refers to the deep groove ball bearing; "7" refers to the angular contact ball bearings; "8" refers to the cylindrical roller thrust bearing; "9" refers to the thrust tapered roller bearings and so on.
Q:How can I remove the belt bearing from the axle 80
Generally, there are three ways to remove bearingsFirst, hit it with a hammer. Be careful, don't break it. To destroy the bearing sleeve, leveraging.First, the lever principle to pry the outside, which requires a support point, usually the bearings in particular in the caseWith Lamar is round Stubbs as you say. There are many models, you can not reach it, for a longer point, and really can not buy their own, three claws longer point is not difficult.You see which method is best for you, too tight down it to spray a little loose liquid, if not then consider heating (it is not only the case)
Q:Why don't belt conveyors use standard bearing housings?
Generally do not use special positioning methods, such as external spherical bearings need to adjust the role of the heart, generally does not use the outer ring bearings. If axial alignment is required, an outer spherical bearing with circlip is recommended.
Q:Spherical bearings * Luoyang domestic spherical bearing holder is required?
3. retaining beam: part of a cage to separate the adjacent cage pockets.4. retaining post: generally cylindrical support, can be used through the roller axial hole.
Q:Such as spherical bearings, if the installation size seat loose,
It should be fixed, fixed, there will be no effect
