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:What are the differences between cylindrical roller bearings nu208m and nu208em?
E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
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: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:Can the Nu and N type NJ NUP cylindrical roller bearings bear axial force?
The answer upstairs is clear. Such bearings can not be designed with axial force. In use, the inner and outer rings of the bearing can have larger axial displacement, and the aim is to compensate the length change caused by the rotating part of the two bearing due to the temperature rise.
Q:The thrust cylindrical roller bearings do not need the bearing seat, and the thrust bearings, shaft rings and seat rings on our unit are all in the bearing seat, often broken. The rotation of the 1. shaft in the bearing seat will not be affected, moreover, the shaft will have radial runout. 2. do not use the bearing seat, usually how to refuel?.Are there any field installation drawings or data on thrust bearings?. Thanks a million!
Hello, I have sent a message to your mailbox, I hope you can help! Have problems you can contact us directly, Beijing Sheng Yi Huitian Electromechanical Equipment Co. Ltd
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:Full use cylindrical roller bearings, uses and advantages?
Otherwise, due to lack of lubrication and high-speed operation will cause more wear and tear. I am a bearing
Q:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
Bearing accuracy grade standards for, divided into 0, 6X, 6, 5, 4, 2, six grades.The accuracy of bearings is increased in order of magnitude 0, which is adequate for general 0, but requires 5 or higher accuracy when used in other conditions or situations.In most cases, it is sufficient to apply KOYO bearings (tolerance grade PN) with general dimensional accuracy and rotational accuracy. When higher requirements are required, the bearings require higher levels of accuracy, for example, the spindle axis of the machine toolBearing. In order to achieve higher precision requirements, the standard specifies the tolerance levels of P6, P6X, P5, P4 and P2. KOYO also specified P4S, SP and UP tolerances for some special bearings in accordance with company standards.
Q:Double row full cylindrical roller bearings, NNCF5008 installation, we need to pay attention to the direction of it?
In theory, cylindrical roller bearings provide radial force, so there should be no direction.
Q:Thrust cylindrical roller bearings, the main use?
Thrust cylindrical roller bearings, the main use? Thrust cylindrical roller bearings are mainly used in oil rigs, iron, steel, machinery and so on.
