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 much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
- The purpose of the shoulder shaft is to limit the axial sliding, of course, as the thrust bearing, the main bearing capacity is the axial force, so the shaft shoulder size can be appropriately larger.
- Q: KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
- Bearing accuracy grade standards for, divided into 0, 6X, 6, 5, 4, 2, six grades.The accuracy of bearings is increased in order of magnitude 0, which is adequate for general 0, but requires 5 or higher accuracy when used in other conditions or situations.In most cases, it is sufficient to apply KOYO bearings (tolerance grade PN) with general dimensional accuracy and rotational accuracy. When higher requirements are required, the bearings require higher levels of accuracy, for example, the spindle axis of the machine toolBearing. In order to achieve higher precision requirements, the standard specifies the tolerance levels of P6, P6X, P5, P4 and P2. KOYO also specified P4S, SP and UP tolerances for some special bearings in accordance with company standards.
- 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: Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master
- Da means shoulder diameter, that is to say, the maximum shoulder size is 69mm, and the minimum is 64mm
- 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
- Q: How should I find the concentricity of cylindrical roller bearings after installation?
- So, in the machining process, try to use special fixtures and parts drawing in tol and other measures to avoid such a remedy".
- Q: What are the components of cylindrical roller bearings?
- The utility model has the advantages of convenient installation and disassembly, especially when the inner, outer ring and the shaft and the shell are in interference fit. Such bearings are generally only used to bear radial load, only the inner and outer ring with single block bearings can bear less axial load or larger intermittent axial load.
- Q: Rolling bearing face to face or back to back on the use of cylindrical roller bearing pairs, the speed limit will be reduced? Please, thank you!
- Rolling bearing face to face or back to back, the speed limit will be reduced? Yes, especially in order to obtain a large preload or a large gap of the matching. Cylindrical roller bearings in pairs, the limit speed will be reduced? Cylindrical roller bearings do not exist in pairs, one said that you can use the same internal and external diameter of double row, four column cylindrical bearings, the same internal and external diameter of double row, four column bearings, compared to single row cylindrical bearings limit speed will be reduced
- Q: Full use roller bearings
- INA full capacity roller bearings have many uses and many applications. Germany FAG bearing group global production of rolling bearings and linear products leading enterprises, not only FAG bearings of good quality, but more importantly, FAG industrial services. In order to extend the life of the railway axle box bearing unit, it is decided that the new FAG axle box bearing unit industry service will be added. We will go to Shanghai FAG bearing China general agent to learn about FAG new axle box bearing units, reprocessing industrial services and other industrial services. The FAG industrial services reprocessing service itself includes thorough cleaning of all bearings, as well as inspection of the dimensions and functions of the entire bearing units. Will re adjust the crankcase clearance, re lubrication SKF bearings, any wear parts will be replaced, if requested by the client, bearing data can also be recorded in the database, for future tracking and review.
- 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).
