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: 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: 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: Full use cylindrical roller bearings, uses and advantages?
In order to make the bearings work properly, the bearings must withstand a minimum load, i.e., C/P<25, in continuous operation.
Q: What are the differences between cylindrical roller bearings nu208m and nu208em?
E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
Q: what does that mean? Please enlighten master, thank you.
Hello, E on behalf of hanging behind the cage (black) steel cage; EM stands for copper holder.
Q: Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master
This is a bit too small to understand, because different installation methods are different from each other. It is recommended that the landlord refer to the installation of cylindrical roller bearings, the above is very clear.
Q: What are the components of cylindrical roller bearings?
Cylindrical roller bearings are usually guided by two blocks of a bearing ring. The cage, roller, and guide ring form a composite, generally separable bearing.
Q: For example, NU, NJ, N, RNU, NUP, NF, NO, NN, RN, what do you mean, who can tell me about that hero?
NU outer ring, double retaining ring, inner ring without edgeNJ outer ring, double retaining ring, inner ring, single edge
Q: Is the nu240em cylindrical roller bearing split?
No, nu240em cylindrical roller bearings are integral.Bearing type: cylindrical roller bearingNew model: NU240EMOld model: 32240EHInternal diameter (mm):200Outside diameter (mm):360Width (mm):58
Q: Cylindrical roller bearingWhat are cylindrical roller bearings, are they available in Kunshan?
This is the simple cylindrical roller bearing rolling body is cylindrical roller, divided into full (no fixed retainer) and belt retainer 2 categories, because the rolling roller, so the axial bearing capacity relative to the ball bearing to be bigger.
