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 are full cylindrical roller bearings?
- Full cylindrical roller bearingCommon cylindrical roller bearings1, single row full cylindrical roller bearingsNCFNJG2 、 double row full cylindrical roller bearingNNCLNNCFNNCNNFTwo, not common full cylindrical roller bearings1, full spherical cylindrical roller bearings2, CARB ring roller bearings
- Q:The thrust cylindrical roller bearings do not need the bearing seat, and the thrust bearings, shaft rings and seat rings on our unit are all in the bearing seat, often broken. The rotation of the 1. shaft in the bearing seat will not be affected, moreover, the shaft will have radial runout. 2. do not use the bearing seat, usually how to refuel?.Are there any field installation drawings or data on thrust bearings?. Thanks a million!
- In general, this kind of bearing does not use the bearing seat
- Q:Full use cylindrical roller bearings, uses and advantages?
- Full cylindrical roller bearings are designed to withstand heavy loads. At the same width, this kind of bearing, compared with the traditional belt cage bearing, has a very high carrying capacity, radial cross-section is small, it can save space, but the speed is relatively low.
- Q:What kind of material is used for cylindrical roller bearings?
- What's the material? The question is not good enough to answer? Usually bearing steel. And stainless steel, plastic. Carbon steel, iron, ceramics, etc.
- Q:In the car there is a cylindrical roller, the size of the diameter of 25mm, the outer diameter of 32mm, width of 9.5mm, who knows what the standard size, have direct purchase Mody, thank you!
- This could be a car only bearing! NSK sample short column can not find the corresponding model!
- Q:Is the nu240em cylindrical roller bearing split?
- Cylindrical roller bearings are generally used to bear radial load, compared with deep groove ball bearings of the same size, with larger radial load capacity, speed limit is closer to the deep groove ball bearing, but the processing with the shaft and the bearing shell with high requirements, allow the inner ring and the outer ring axis axis inclination is small (2 degrees -4 two degrees), such as the axis is tilted beyond the limits, contact roller and raceway will worsen, seriously affect the load bearing capacity, reduce the service life of the bearing.
- Q:How are the twin row cylindrical roller bearings classified?
- Double row cylindrical roller bearings have cylindrical inner bore and conical inner bore (bearing rear code plus K) two structures. This kind of bearing has the advantages of compact structure, large rigidity, large bearing capacity and little deformation after load. It is especially suitable for spindle support of machine tools. The conical inner hole can also play the role of micro adjustment of the clearance, and can simplify the positioning device structure, and is convenient for installation and disassembly.
- Q:cylindrical roller bearings N210 20Deep groove ball bearings 6120, self-aligning ball bearings 1210, cylindrical roller bearings N210 in the same radial force conditions, the life expectancy of the three levels and how to compare? What is the cause of the high and low?
- Summary: the above three kinds of bearings, the service life in accordance with the order from high to low: deep groove ball bearings, self-aligning ball bearings, cylindrical roller bearings.
- Q:Why are there no double row cylindrical roller bearings in the mechanical design manual?
- Normally, the inner diameter of the bearing should be in interference fit with the shaft (for some light loads, too, with a transition fit).
- Q:For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12
- This is the outer ring and the inner ring can be separated, the bearings in the country can be produced, imported bearings are sold.Another model is up to your standard,Cylindrical roller bearings SL183008Semi position bearing, full cylindrical roller, dimension series 30M 0,31 kgqualityCr 66000, NBasic rated dynamic load, radialC0r 67000, NBasic rated static load radialCur 11200, NFatigue limit load, radialNG 6300, 1/minLimit speedNB 4300, 1/minReference speed
