Specification of Cylindrical roller bearings:


Cylindrical roller bearings belong to separable bearings, whose inner and outer rings are linearly contacted with rollers. They have small friction coefficient, bigger capacity of bearing  radial load and are applicable to both bearing heavy load and impact load and high-speed rotation. Cylindrical roller bearings have the advantages of compact structure, strong stiffness, big bearing capacity, small deformation after loaded etc.

CNBM has already successfully developed split cylindrical roller bearings which can be freely installed at any time and any place, to meet the demand of driving and conveying rollway bearings at cooling area of continuous casting. CNBM also can provide special cylindrical roller bearings according to requirement of customers.


Product Application: 


- Iron and steel metallurgical industry

- Medium and large motor

- Generator

- Combustion engines

- Machine tool spindle

- Speed reducer

- Loading and unloading machinery and all kinds of industrial machinery



Single row cylindrical roller bearings


- NU, N single row cylindrical roller beaings

NU type and N type allows axis relative the cage within the scope of certain to do axial movement, it would adapt for thermal expansion or installation error caused by the shaft and housing relative position changes, they suit to use for free end bearing. Because they can not limit shaft and the shell axial displacement, and  can only bear the radial load.


- NJ, NF single row cylindrical roller bearings

Both NJ and NF can bearing single direction axial load in a certain extent.


- NUP single row cylindrical roller bearings

NUP type bearings with double outer rid, single inner rid and  loose rid, this design is possible to limit the axial displacement of the shaft or the housing in double direction within the scope of the axial clearance. in addition they mainly used to bear radial load, also can withstand diameter, the axial union load. Therefore this NUP suitable for fixed end bearings.


- NCL…V single row cylindrical roller bearings

No outer rim but with double lock ring without cage cylindrical roller bearing.

The bearing no cage, roller number is more, and size of the same other cylindrical roller bearing is able to withstand the big radial direction load, but its limit rotational speed is low. The bearing inner ring and outer inseparable, cannot install respectively, can limit shaft or housing of the two directions of the axial displacement in bearing axial clearance within the limit.

Q: Gb/t283 cylindrical roller bearing age number?
Hello, it's 2007.GB/T 283-2007 roller bearings cylindrical roller bearings overall dimensionsStandard number: GB/T 283-2007Rolling bearings - cylindrical roller bearings - DimensionsRolling bearings - cylindrical roller bearings - DimensionsEnglish, Name:Rolling, bearings - Cylindrical, rolling, bearings - Boundary - Dimensions
Q: How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
The shoulder height (diameter) shall be smaller than the big diameter of the bearing (less than 42), mainly for easy unloading.
Q: How to check the thrust cylindrical roller bearings?
Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).
Q: Can you make it clear? I don't understand. Thank you for being here first.
Oh, My God!!! Do you understand the bearings in this way?! What is called "roller" means that the rolling column is cylindrical and similar to cylindrical shape, such as short cylindrical, long cylindrical, tapered roller, spherical roller, etc.." This kind of statement should be listed as the promotion answer!!! Absurd! Laughable! !!The standard answer is: Bearings in accordance with the direction of force, divided into radial bearings and thrust bearings, in simple terms, if the main force to bear the axial thrust bearings, thrust bearings; otherwise, that is, radial bearings. As for radial roller bearings, simply speaking, it is the roller bearings that mainly bear radial forces. It's so simple, there's so much nonsense!!!
Q: My notes is the former has a taper hole on the cone position preload, the latter is a nut. But the online information seems a little different. Are the preload methods for two direction thrust angular contact bearings and angular contact ball bearings the same?
The latter is mainly used as a precision screw shaft for the radial motion and axial runout requirements are very strict, generally used when they are two back-to-back, when pre tightening have strict requirements, general requirements for the radial motion and axial runout should not exceed 5 per thousand mm.
Q: Can cylindrical roller bearings bear high temperature?
Bearing is not high temperature grease is not high temperature, a grease temperature does not exceed 120 degrees, high temperature will lead to bearing lubrication performance, unable to work, in fact, the bearing itself can be high temperature resistant.
Q: What are full cylindrical roller bearings?
Full capacity roller bearings are divided into double row full load roller, single row full roller, outer spherical roller, CARB bearingsI am a bearing manufacturer, factory direct marketing, welcome inquiry cooperation. Contact information on personal data
Q: What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
The logarithmic curve roller is also a convex roller, which belongs to a full convex roller;The shape roller refers to a roller which has a slight modification to the diameter of the outer end of the roller to prevent the stress concentration at the end of the contact between the roller and the raceway.The corresponding types of bearings are cylindrical roller bearings and tapered roller bearings. Modified roller and convex roller have been widely used in domestic roller bearings, which can improve the service life of the products.
Q: For example, NU, NJ, N, RNU, NUP, NF, NO, NN, RN, what do you mean, who can tell me about that hero?
NN double row cylindrical roller bearing inner ring gear side no outer wallRN no outer ring type N cylindrical roller bearing
Q: Cylindrical roller and bearing outer ring processing is sheet metal forming?
Bearing parts, the main size tolerances are fighting between 0.01 mm, ultra poor 1/1000 mm, are scrap. Tolerances for precision bearings are extremely stringent, such as the diameter of each steel ball (or roller) and the diameter of the inner and outer rings. Surface hardness of more than HRC60 (as a metal cutting tool material of high-speed steel, hardness is HRC65-68). High quality bearings, these are strictly controlled.
