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: 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: How are the twin row cylindrical roller bearings classified?: The NN0000K type conical bore double row cylindrical roller bearingThis kind of bearing is compact in structure and bears little deformation under load, so it is suitable for the support of spindle of machine tool. The inner bore of the bearing is taper, and the radial clearance of the bearing can be adjusted slightly.This kind of bearing with no outer wall, so you can install the outer ring and the inner ring assembly respectively (with roller and cage), does not limit the axial displacement of the shaft or shell, cylindrical roller bearing with the same radial size is compared, can bear larger radial load.

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: Double row full cylindrical roller bearings, NNCF5008 installation, we need to pay attention to the direction of it?: In theory, cylindrical roller bearings provide radial force, so there should be no direction.

Q: How to check the thrust cylindrical roller bearings?: This data is the minimum axial load, not the maximum axial load.

Q: what does that mean? Please enlighten master, thank you.: Hello, E on behalf of hanging behind the cage (black) steel cage; EM stands for copper holder.

Q: What is the maximum rotational speed of a single row full cylindrical roller bearing?: FAG double row full cylindrical roller bearingsFAG double row full roller cylindrical roller bearings can withstand the radial load and axial load, but also can withstand overturning moment, so they are often used as fixed bearings. The outer ring of the NNC 49V series bearing has a lubricating tank and a number of lubricating holes, which can also be lubricated in the shaft during operation. The NNF50B.2LS.V and NNF50C.2LS.V series of bearings are sealed in both ends, and the seals are filled with grease. With better service conditions, the grease can reach the working life of the bearing. Lubrication can be carried out by lubricating grooves and lubricating holes on the outer ring. If the same number of bearings are mounted on one shaft, the outer ring can vary in speed because the outer ring is narrower than the inner race. The utility model is suitable for a pulley mechanism, so that the pulley can be easily fixed on the outer ring of the bearing, and both ends of the outer ring of the bearing can be provided with an annular groove with an elastic retaining ring.

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?: The cylindrical roller bearings are in line contact with the outer ring of the bearing, and have the largest contact surface with the outer ring of the bearing. And the large contact surface means that in the same radial force, the same speed, friction, and thus generate more heat, and thus affect the life.

Q: What's the difference between imported bearings and imported bearings?: Domestic bearings used in the cage and rivet and washer, spacer ring, sealing ring, pillar, pin etc. the material is divided into black metal materials (such as low carbon steel, stainless steel etc.), non-ferrous metal materials (such as brass, bronze and Aluminum Alloy etc.) and non metal materials (such as plastics, phenolic textolite three) etc..

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.
