Product Description:

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 can angular contact be distinguished from the front and back? What are the characteristics of each?
The front outer ring is wide and the outer back is narrow.
Q:Do angular contact ball bearings come with a sealing cap?
Angular contact ball bearings generally have no dust caps or seals. You can design and install an oil seal or something like that.
Q:What does angle contact back to back mean?
Angular contact ball bearings are interesting bearings. Divided the face and back. And others, ha ha.See young lovers not.Happy time, hold together KISS, KISS is certainly the mouth to mouth, face to face, we use the word FACE to English it said about this status.  When angry, who also ignore, two people are turned away, back to back, this is back to back, we use the word BACK to English it said about this status.Whether back-to-back or face-to-face, it must be by a movement of two or more than two people to complete (a person, it had to go in front of the mirror), we have two people to do that, we use DOUBLE to represent these two individuals.DOUBLE: twoFACE: faceBACK: backSee the above three words, no, very clever, angular contact ball bearings also say so.On behalf of the two sets of bearings with DOUBLE - is a "D",Using FACE for face to face, shorthand is a "F"",BACK - back to back, is a "B".OK, now came out in angular contact ball bearings inside the two face is bearing code BF, two back-to-back bearing is DB.
Q:The difference between ultra high speed angular contact ball bearings and other plain bearings
The roller of angular contact ball bearings is ball, because it is a point contact (different from roller bearing line contact), so it can provide higher speed, smaller heating quantity and higher rotation precision. In some high speed spindle applications, ceramic ball hybrid bearings will also be used. Compared with the traditional steel ball, the characteristics of ceramic ball materials endow the ceramic ball bearings with high rigidity, high speed, high temperature resistance and long service life, so as to meet the customers' demand for machine tool bearing products. (flight five Rui reminded you, at present, the mainland ceramic ball mixed bearings spot less, in your choice of such imported bearings, you need to pay attention to delivery time).On the contact angle of angular contact ball bearings, 15 popular and the contact angle of 25 speed; high performance usually contact angle of 15, while the axial contact angle of 25 with high bearing capacity. Due to the effect of preload contact application of ball bearings for precision angle is very large, such as high load capacity, high rigidity of the occasion, will generally choose bearing pre medium or heavy load; and for some applications of high speed and high precision, in the early selection of imported bearings, need to pay attention to choose the appropriate pre load. Pre load is generally divided into light, medium, heavy three kinds, generally light preload is more common. In order to facilitate the use of customers, the general will have universal matching, precision angular contact ball bearings. This type of imported bearings eliminates the customer's preload adjustment, thus saving installation time.
Q:How many angles are there in angular contact ball bearings? How many degrees are they?
A stands for 30 degrees, A5 stands for 25 degrees, B stands for 40 degrees, and C stands for 15 degreesThe new Seiko NSK serves you!
Q:Two angular contact ball bearings, the use of clearance problems
Bearing in pairs need not be adjusted! The bearing is marked with letters!DB: back to backDF: face to faceDT: series connectionSU: single arbitrary combinationDU: any combination of two bearings.There is also a combination of three columns and four columns with letters on each bearing!Among them, when selecting the SU mark bearing, it is necessary to choose the bearings with the most close tolerance of the inner and outer ring diameter together. Clearance adjustment is also relatively easy.It is difficult to pair the bearings by adjusting the two common bearings together by adjusting the experience. It is best not to try in such a strict place!
Q:What is angular contact ball bearing contact angle?
The angle between the imaginary line of the contact between the roll and the raceway and the vertical line of the axis of rotation
Q:Can angular contact ball bearings be adjustable?
You say, of course notHave you seen when you spend RMB Mingbi useful
Q:What are the differences between angular contact bearings and deep groove ball bearings?
Deep groove ball bearings and angular contact ball bearings with inner and outer diameters and wide dimensions have the same inner ring size and structure, but have different outer ring sizes and structures:1. deep groove ball bearings, outer raceway, both sides of the double shoulder, and angular contact ball bearings generally single shoulder;2. deep groove ball bearings, raceway curvature and angular contact ball is different, the latter is often greater than the former;3. deep groove ball bearings, outer raceway and angular contact ball bearings of different, non central position, the specific value of angular contact ball bearings designed to be considered, and the degree of contact angle related;In terms of use:1. two different purposes, suitable for deep groove ball bearings bear radial force and smaller axial force, axial and radial load and combined load torque, and angular contact ball bearings can withstand axial load, radial load is larger (with different contact angles and loads of different sizes), double matching (with matching mode vary) is two-way can withstand axial load and torque load.2., the limit speed is different, the same size of angular contact ball bearings, the ultimate speed is higher than deep groove ball bearings.With type, size, precision, and so on.
Q:What are the differences between angular contact bearings AC and A and C?
AC is the code for homemade bearings. The contact angle is 25 degrees. It is subjected to axial force and radial forceA for Japan bearing angle code, contact angle of 30 degrees, to bear axial force and radial forceC is the bearing angle code of Japan. The contact angle is 15 degrees. It mainly bears radial force and small axial force. It is used in high precision and high speed equipment
