Four row cylindrical roller bearings

Four row cylindrical roller bearing is usually use in rolling mill’s work roll or back-up roll. It mainly take much radial load, which is extensively used on the work roll of wire rod mill, section mill and bloomer mill , as well as the back-up roll of dressing machine, cold rolling mill and hot rolling mill.There are three kinds of structures: FC, FCD, FCDP. There are three grades for tolerance : 0 , 6 , 5.


FC: double outer ring, single inner ring, inner ring without rid;

FCD: double outer ring, double inner ring, inner ring without rid;

FCDP:double outer ring, double inner ring, inner ring without rid



★ Product Features:

The rollers of the cylindrical roller bearing are usually guided by two flanges of a ring.

Because this assembly part composed of cage, roller and guide ring can be separated from

another ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing

can be easily mounted and dismounted. Its advantages are obvious especially when there is

interference fits between the inner, outer ring and the axis, housing.

This bearing is usually subjected to radial load, only the single-row bearing with inner& outer

rings flanges can bear small steady axial load or great intermittent axial load. It has a high

requirement on the processing of the fitting parts such as axis and housing bore, etc.


Product Application: 

Cylindrical roller bearings are mainly used for:

- Iron and steel metallurgical industry

- medium and large motor

- generator

- combustion engines

- gas tuibine

- machine tool spindle

- speed reducer

- loading and unloading machinery and all kinds of industrial machinery


Four Cylindrical Roller Bearings Catalugue











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: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!
Bearing (Bearing) is an important component of modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement and guarantee its rotation accuracy.According to the friction property of the moving element, the bearings can be divided into two kinds: rolling bearing and sliding bearing. Among them, the rolling bearing has been standardized and serialized, but compared with the sliding bearing, its radial dimensions, vibration and noise are relatively large, and the price is higher.Generally, the rolling bearings are composed of four parts: the outer ring, the inner race, the rolling body and the cage. According to the shape of the rolling element, the rolling bearings are divided into two major categories: ball bearings and roller bearings.
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: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:What is the limit speed and rated dynamic load of NSK full M40-19g cylindrical roller bearings, HTF?
NSK bearing type suffix solution of NSK bearing type by the basic code, prefix and post code, the basic code bearing series (including type) diameter and contact angle; pre code specific bearing; post code structure shape, bearing size, material, seal, retainer, clearance, heat tolerance processing, lubrication, change and other technical requirements, in addition to the basic code added after bearing code. NSK bearing model prefix F - deep groove ball bearing with flange outer ring (for D less than 10 mm), for example: F605. HR - high load tapered roller bearings, for example: HR30207J. MF - Flanged, outer race, deep groove ball bearings of specified sizes (D less than 10 mm), MF52. MR - deep groove ball bearings of specific size (for D less than 10 mm), for example: MR31. NSK bearing type rear code (1) internal structure A - internal design and standard different bearings. A - angular contact ball bearings with a contact angle of 30 degrees. A5 - angular contact ball bearings with a contact angle of 25 degrees. B - angular contact ball bearings with a contact angle of 40 degrees. C - angular contact ball bearings with a contact angle of 15 degrees. C - tapered roller bearings with a contact angle of 20 degrees.
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:How much is the axial force of double row cylindrical roller bearings? How is it calculated?
The cylindrical roller bearings have ribs can withstand certain axial force, the axial force for cylindrical but still belongs to the non normal stress, can cause early failure of the bearing, it is generally not given the axial bearing capacity, no formula
Q:Double row full cylindrical roller bearings, NNCF5008 installation, we need to pay attention to the direction of it?
Double row cylindrical roller bearings have no directionality, so they do not need to pay attention to the direction! However, it should be noted that the inner ring and outer ring should be positioned separately to prevent axial movement!
Q:Can it be used for axial alignment? Forty-fiveWhat is the function of the flat retaining ring of NUP cylindrical roller bearings with flat retaining rings? Can it be used for axial alignment?How much axial force can I bear then?You are the ZWZ? Can you make a friend?!How much axial force can you bear? Do you have a formula or a recommended value?NUP is needle roller bearings, brothers, I dialed the wrong number:What is the function of the flat retaining ring of the needle roller bearing with flat ring NUP? Can it be used for axial alignment?There seems to be no experts here, all mixed up
Yes, the function of the flat ring is to bear the axial force and be used for axial positioning.
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..
