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 are the twin row cylindrical roller bearings classified?: Classification of double row cylindrical roller bearings:The NN0000 type cylindrical roller bearingsThe bearings are compact in structure and small in deformation under load, so they are especially suitable for the support of the spindle of machine tools. Because of its no outer wall, so you can install the outer ring and the inner ring assembly respectively (with roller and cage), does not limit the axial displacement of the shaft or housing, compared with the single row cylindrical roller bearing with the same radial size, can bear larger radial load.

Q: How to check the thrust cylindrical roller bearings?: However, in the conventional design, there are few checking bearings, as long as the shaft and shell meet the intensity requirements on the line, because the manufacture of bearings than ordinary mechanical parts to be much more stringent (except shoddy products).If you do your homework, do it according to the design manual.

Q: Can the Nu and N type NJ NUP cylindrical roller bearings bear axial force?: The answer upstairs is clear. Such bearings can not be designed with axial force. In use, the inner and outer rings of the bearing can have larger axial displacement, and the aim is to compensate the length change caused by the rotating part of the two bearing due to the temperature rise.

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: Hello, according to your descriptionCylindrical roller bearings NN3008-AS-K-M-SPAccording to the main dimensions of the DIN 5412-4 standard, non locating bearing, double row, with taper hole taper 1:12, can be separated, with cage, radial internal clearance decreased, tolerance limitInternal diameter D 40 mmOuter diameter D 68 mmThe thickness is B 21 mmDa Max 63 mmDb min 62 mmD1 50,6 mmDa min 45, mm, DS, 3,2, mmE 61, mmNS 4,8 mmRA Max 1 mmRmin 1, mmS 1,4 mmAxial offset from the center positionM 0303, kgqualityCr 45000, NBasic rated dynamic load, radialC0r 58500, NBasic rated static load radialNG Fett 12000 1/minLimit speed of grease lubricationNG l 15000 1/minLimit speed at least oil lubricationCur 8400, NFatigue limit load, radial

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: Is the roller bearing and the bearing chamber movable in the tapered rotor motor?: E in cylindrical roller bearing is the meaning of improving internal cage design, similar to the SKF cylindrical roller bearing EC form, this type of bearing than without E, is to strengthen the design, the roller is filled more larger to increase the load. From the load point of view, it is better to choose E.

Q: What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?: The logarithmic curve roller is also a convex roller, which belongs to a full convex roller;The shape roller refers to a roller which has a slight modification to the diameter of the outer end of the roller to prevent the stress concentration at the end of the contact between the roller and the raceway.The corresponding types of bearings are cylindrical roller bearings and tapered roller bearings. Modified roller and convex roller have been widely used in domestic roller bearings, which can improve the service life of the products.

Q: Why are there no double row cylindrical roller bearings in the mechanical design manual?: but they move axially with the roller and the outer ring?If so, the cylindrical roller bearings without bearings on both sides of the bearing should be normal

Q: Cylindrical roller and bearing outer ring processing is sheet metal forming?: Sheet metal forming? You think too simple. Do you know that a key technical parameter of a machine part is called tolerance? The inner and outer rings and roller rolling bearings (ball, roller) have strict tolerance requirements, but also requires a very high hardness and abrasion resistance, the general is the use of special alloy steel, rolling (usually hot) heat treatment after forming, after precision machining (turning, grinding etc.) after finished product.
