Specification of Double Row Cylindrical roller bearings:

Double row 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

Double row cylindrical roller bearings

- NN double row cylindrical roller bearings

This kind of bearings with inner rid, no outer rid. This assembly part can be separated from another ring, and they have larger radial load capacity than other single row cylindrical roller bearings with the same size, but the axial or housing is free axial displacement, so this kind of bearings can only bear the axial load.

- NNU, NNU…K double row cylindrical bearings

NNU,NNU...K type bearings with outer rid, no inner rid. There are tow kinds of holes, one is cylindrical hole, and another is tapered hole. Axial or housing is free axial displacement, so this kind of bearings can not bear the axial load. But these kind of bearings have larger radial load capacity than other single row roller bearings with the same size.

- 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.

- NNCF double row cylindrical bearings

NNCF type bearings with three inner rids and one outer rid. They can take a direction axial positioning. There is a fixed ring in the other side of the outer rid, it can make bearing keep as one.

Q:Can cylindrical roller bearings bear high temperature?: Bearing is not high temperature grease is not high temperature, a grease temperature does not exceed 120 degrees, high temperature will lead to bearing lubrication performance, unable to work, in fact, the bearing itself can be high temperature resistant.

Q:Cylindrical roller bearings, in the grease after the operation for a short period of time, the grease was thrown out (thrown to the end cap), resulting in roller and raceway between the lack of grease, lubrication poor. Decomposition found that the roller has round circumferential friction marks, but also on the roll, but compared to the roller is very slight. And there are relatively sound bearings, abnormal sound.Is this phenomenon normal? What if it doesn't work? What was the reason? What's the solution? StopThanks for your help!Assuming the grease is no problem, viscosity, consistency, selection is no problem If exclusion is the problem of grease, what other reasons can this be the case? ?: Grease over dry, thin will affect the effect, but also with the brand of grease is also related, you can try several kinds of grease, to see what kind of effect is bestChangshou City Kazakhstan axis electrical and mechanical materials trade, we are agents of a variety of well-known bearings

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:Cylindrical roller bearingWhat are cylindrical roller bearings, are they available in Kunshan?: This is the simple cylindrical roller bearing rolling body is cylindrical roller, divided into full (no fixed retainer) and belt retainer 2 categories, because the rolling roller, so the axial bearing capacity relative to the ball bearing to be bigger.

Q:Gb/t283 cylindrical roller bearing age number?: Hello, it's 2007.GB/T 283-2007 roller bearings cylindrical roller bearings overall dimensionsStandard number: GB/T 283-2007Rolling bearings - cylindrical roller bearings - DimensionsRolling bearings - cylindrical roller bearings - DimensionsEnglish, Name:Rolling, bearings - Cylindrical, rolling, bearings - Boundary - Dimensions

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:Why should the main shaft be coupled with double row cylindrical roller bearings?: Separable, easy to install and disassemble, mainly used in lathe, milling machine, machining center and other high-precision machine tool spindle. Hope to be of help to you.

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!: Hello, according to the data you supplied, and the type of bearing you saidAfter my inquiry,Cylindrical roller bearings, without this specification, GB specifications are 25 diameter, 52 outer diameter height, 15 model is nu205eAlso, the inside diameter is 25, the outside diameter is 62, the height is 15. The model is nu305eGB specifications, I have herecontactLook at personal data

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:How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings: First of all for the bearing clearance calculation is a very complicated problem, because the bearing structure of different types, and the usage of different materials, the temperature of different factors such as the clearance is different, and because of the different structure types and some bearing bearing clearance is divided into radial clearance and axial clearance; also need to pay attention to the bearing clearance is usually divided into the following 1. conditions, clearance before installation, usually refers to the bearing manufacturers factory according to the standard to determine the clearance of bearing clearance. 2., after the installation clearance, because the bearing inner ring and the shaft is interference fit, when the bearings installed on the shaft, its inner ring will be as the amount of interference and expansion, resulting in smaller clearance of bearings. 3. clearance work, because the bearing is affected by load and rotating friction in the work, the temperature will gradually increase, will cause the bearing inner ring further expansion, which will make further changes in bearing clearance. However, the main clearance of the bearing is the largest (minimum) diameter of the raceway of the outer race of the bearing, the largest (minimum) diameter of the rolling body and the largest (smallest) diameter of the raceway of the inner race. For example, cylindrical roller bearings, its largest clearance = outer raceway raceway, maximum diameter of -2* roller minimum diameter - inner raceway minimum diameter derived, and conversely, for the smallest clearance. The average user of bearings actually doesn't need to know that.The other 23226 models should be the spherical roller bearing, not double row cylindrical roller bearing.I hope my answer will be of some help to you!
