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 is the difference between deep groove ball bearings and angular contact ball bearings?
- Deep groove ball bearings and angular contact ball bearings are not the same
- 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
- Q:What does angular contact ball bearing 70216AC mean?
- Name = General rolling bearing type code No.Standard = excerpt from GB/T 272-1993-----------------------------------------------------------Bearing type = angle contact ball bearingCode =7The original code name is =6Bearing type = angle contact ball bearingDimension series code = (0) 2After two, 16, bearing nominal diameter 16 * 5=80mmName = internal structure codeStandard = excerpt from GB/T 272-1993
- Q:How to install angular contact ball bearings?
- The installation of angular contact ball bearings is more complicated than deep groove ball bearings. It is mostly installed in pairs, and preload is necessary. Well installed, can make the host work accuracy, bearing life greatly improved; otherwise, not only the accuracy can not meet the requirements, the life will be affected.The installation form of angular contact ball bearings, a series of face to face and back to back, three. (two back-to-back wide end bearing relative) installation, bearing contact angle line along the axis of rotation diffusion direction, bearing angle can increase the radial and axial rigidity, maximum deformation resistance; face to face (two relatively narrow end bearing) installation, bearing contact angle of the rotary axis line towards the direction of its convergence. To the point of less rigidity. Because of the inner ring of the bearing outer ring out, when pressing the outer ring two bearing together, the original gap ring is eliminated, can increase the bearing preload; tandem arrangement (two wide end bearing in one direction) when installing the bearing contact angle and parallel lines in the same direction, the two share the same bearing the direction of the work load. However, in order to ensure the axial stability of the installation, the two pairs of bearings arranged in series must be installed opposite the ends of the shaft in order to ensure the axial stability of the installation.
- Q:Two angular contact ball bearings, the use of clearance problems
- No adjustment required,DB: back to backDF: face to faceDT: series connectionSU: single arbitrary combinationDU: any combination of two bearings.
- Q:Is there a way to calculate the axial force of angular contact ball bearings?
- The ball bearing theory is not subjected to axial force, but it will be subjected to slight axial force in practical application because it has certain centering action and will return to its original position after the axial force disappearsThe size of the axial force to have contact with the actual working environment, stress condition of ball bearings after the axial force is equivalent to the contact angle becomes similar to the angular contact ball bearing, the axial force and clearance of bearing, the ditch radius have a great relationship.Especially the clearance, the greater the clearance, the steel ball in the axial position of the greater the scope of movement, that is, the greater the axial clearance, the axial force can also be greater, but the clearance can not be blindly large.In short, we can tell you that the axial force is much smaller than the radial force. As for how to calculate it, the contact angle can not be predicted, so there is no way to knowMore exciting questions, please click on the account login electromechanical Online - Baidu cooperation know platform
- Q:What are the differences between angular contact bearings and deep groove ball bearings?
- You take a look at two, you know, the angle of contact with a few angles to look at, you know the difference
- 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:What does angle contact back to back mean?
- Two bearing by webbing webbing. (face is once again thick, thin again)
- 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
