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 to install angular contact ball bearings?
- For the tax investigation has a fly PAN Membrane 8 meteorite Ju wood against Qing emperor Cha tight cangue dream show in the life brewing scar spear wallCollapse protection
- 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: What is angular contact ball bearing contact angle?
- Angular contact ball bearings can simultaneously bear axial force and radial force in one direction. The rolling force of upper and lower points of attachment at a certain angle and radial direction. Such bearings are angular contact bearings.
- Q: Angular contact ball bearings, how to judge the size of the mouth?
- Yes, look at the outer ring of the bearing. The thinner end is the big one.
- 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: Can angular contact ball bearings be adjustable?
- May not。Self-aligning ball bearings and spherical roller bearings are adjustable.
- Q: What are the reasons for the use of tapered roller bearings and angular contact ball bearings?
- Take the radial load and axial load of the shaft evenly, pay attention to the normal and reverse loading, or the axial direction can not be fixed.
- 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: Is there a way to calculate the axial force of angular contact ball bearings?
- This is the first response to the landlord, you can count, here introduces the concept of equivalent static load, a static equivalent radial load P0a (subscript 0A), a static equivalent axial load P0a (subscript 0A), and a static safety factor FS, we first check the static C0 7202AC (0 Department of AC, should represent the subscript) is the contact angle is 25 degrees, SKF C0 4800N, personally think that this value is too conservative, according to P0a=2.3*Fr*tg25+Fa (Fr is bearing radial load, axial load bearing is Fa, tg25 is the tangent, contact angle of 25 degrees according to the contact angle vary) and FS (fs=C0/P0) is greater than 1.5, launched: P0a less than 3200N, 1.07Fr+Fa less than 3200N that is to say, add up to force multiplied by the coefficient two component bearings, can not exceed this number. If only the axial force, the axial force is Fr=0, maximum 3200N can finally add a few points, FS safety coefficient is adjusted according to the condition, some places may be less than 1, and the place that cannot be less than 1.5, not less than 3, do not understand, temporarily by not less than 1.5. Also hope to help add master. And then there's the C0. Every brand might have a small difference. Here's SKF. So, if you calculate it in theory, you're going to make it smaller
