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 should I find the concentricity of cylindrical roller bearings after installation?
- Any form of assembly, adjustment center is a very troublesome thing, but also in the measuring installation is not very complete, the usual method is to in the base below (or below) thin copper with different thickness, until you feel better, but each installation to re adjust.
- Q:Can you make it clear? I don't understand. Thank you for being here first.
- The rollers refer to the rolling bodies as cylinders and similar cylindrical shapes, such as short columns, long columns, tapered rollers, spherical rollers, etc..
- 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: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:NSK cylindrical roller bearings EW/EM series of differences and characteristics
- E international is called "reinforced type" load, also means to increase rolling bodyW international is called a steel cage
- Q:Cylindrical roller and bearing outer ring processing is sheet metal forming?
- Bearing parts, the main size tolerances are fighting between 0.01 mm, ultra poor 1/1000 mm, are scrap. Tolerances for precision bearings are extremely stringent, such as the diameter of each steel ball (or roller) and the diameter of the inner and outer rings. Surface hardness of more than HRC60 (as a metal cutting tool material of high-speed steel, hardness is HRC65-68). High quality bearings, these are strictly controlled.
- Q:What is the maximum rotational speed of a single row full cylindrical roller bearing?
- FAG single row full cylindrical roller bearingsFAG single row full cylindrical roller bearings can bear large radial loads, and can also bear single direction axial load. Axial positioning can be guaranteed by a symmetrical arrangement of similar bearings. NCF, 29V, NCF, 30V series of bearings have two fixed inner ring, the outer ring has a baffle, they can only bear the direction of the outer edge of the fixed axial load. The NJ23VH series bearings can bear the axial load toward the inside of the inner ring, and their rollers are fixed in the outer ring, even if the inner ring is taken away. The two rings are tight fit, easy installation and disassembly.
- 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!
- Cylindrical roller bearings themselves require that the applied speed can not be too high, especially in short axis applications
- Q:Why are cylindrical roller bearings suitable for traveling support?
- Should be the inner ring and the outer ring without the edge of the can do moving support.
- Q:Why cylindrical roller bearings can not bear axial load?.
- The thrust bearing retainer plate and two pieces of circular hole of the ball and the ball hole and shaft wear in the park, circular plate, steel ball track between two plate, shaft and the bearing seat of the top plate in the round two sides, in addition to the track groove, it is not binding the radial direction, so it cannot withstand the radial load.The radial bearing by the size of the two steel ring, steel ball size between steel ring, steel ring diameter fixed by a bearing seat, shaft mounted on a small steel ring, binding only in the radial direction and axial direction of the load is not binding, so it cannot withstand the axial diameter.
