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: KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
- The processing of the mating surface, especially the mating surface, is not done in a single clamping. The use of the bearing seat also causes misalignment, such as a flange bearing seat or a vertical KOYO inlet bearing block. As the work load causes the shaft to bend and deform, and also causes the inner and outer ring of the bearing to tilt, it will also appear misalignment.The main products are: KOYO bearing rolling bearing, deep groove ball bearings, high precision bearings, self-aligning bearings, bearings, plane ball bearings, cylindrical roller bearing, linear guide bearing, ball screw bearings, miniature linear guide bearing, cross roller guide bearings, reciprocating rotary bearings, ball bearing slide bushing, group cam follower.
- Q: Double row full cylindrical roller bearings, NNCF5008 installation, we need to pay attention to the direction of it?
- Double row cylindrical roller bearings have no directionality, so they do not need to pay attention to the direction! However, it should be noted that the inner ring and outer ring should be positioned separately to prevent axial movement!
- Q: cylindrical roller bearings N210 20Deep groove ball bearings 6120, self-aligning ball bearings 1210, cylindrical roller bearings N210 in the same radial force conditions, the life expectancy of the three levels and how to compare? What is the cause of the high and low?
- The cylindrical roller bearings are in line contact with the outer ring of the bearing, and have the largest contact surface with the outer ring of the bearing. And the large contact surface means that in the same radial force, the same speed, friction, and thus generate more heat, and thus affect the life.
- Q: Why cylindrical roller bearings can not bear axial load?.
- Bearing bearing axial force or radial force is determined by the structure of the bearing, thrust ball bearings are also called plane bearings, which are mainly used to bear axial force; cylindrical roller bearings can bear radial forces and are not suitable to bear axial force.
- Q: For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12
- This is the outer ring and the inner ring can be separated, the bearings in the country can be produced, imported bearings are sold.Another model is up to your standard,Cylindrical roller bearings SL183008Semi position bearing, full cylindrical roller, dimension series 30M 0,31 kgqualityCr 66000, NBasic rated dynamic load, radialC0r 67000, NBasic rated static load radialCur 11200, NFatigue limit load, radialNG 6300, 1/minLimit speedNB 4300, 1/minReference speed
- 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 are the components of cylindrical roller bearings?
- Compared with the deep groove ball bearings of the same size, this kind of bearing has larger radial load capacity, and is also suitable for high-speed rotation from the structure.
- 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!
- In general, this kind of bearing does not use the bearing seat
- Q: Can it be used for axial alignment? Forty-fiveWhat is the function of the flat retaining ring of NUP cylindrical roller bearings with flat retaining rings? Can it be used for axial alignment?How much axial force can I bear then?You are the ZWZ? Can you make a friend?!How much axial force can you bear? Do you have a formula or a recommended value?NUP is needle roller bearings, brothers, I dialed the wrong number:What is the function of the flat retaining ring of the needle roller bearing with flat ring NUP? Can it be used for axial alignment?There seems to be no experts here, all mixed up
- Yes, the function of the flat ring is to bear the axial force and be used for axial positioning.
- Q: Why should the main shaft be coupled with double row cylindrical roller bearings?
- Because double row cylindrical roller bearings with high carrying capacity, high precision, separation, easy installation and disassembly, mainly used in lathes, milling machines, machining centers and other high-precision machine tool spindle. Hope to be of help to you.
