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:Which column roller bearing brand is good?: Foreign SKF is better, the domestic is Kazakhstan axis, and then is Taiwan's Rui Rui, you can look at yourself, they recently in the Qingdao market to great influence, you can understand.

Q:Why does cylindrical roller bearings fail abnormally?: 3, the rigidity of the shaft is poor, too large bending occurs under the load, and the span of the fixed end of the cylindrical roller bearing two is larger. When the temperature rises, the thermal elongation of the shaft causes the bending of the axle static property.4. The assembly surface falls into the hard particle or the dirt, the stress concentrates, to the open bearing pedestal when clamping, the cylindrical roller bearing ring clamp flat.

Q:What does "cylindrical roller bearing" ENV mean?: Cylindrical roller bearings, the basic model suffix ENV meaning:E: enhanced design with improved bearing load capacityN: the outer ring of the bearing is provided with a stopping grooveV: full installed roller (no cage)

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:Why are cylindrical roller bearings suitable for traveling support?: Cylindrical roller bearings without inner sides of the inner ring or outer ring, whose inner and outer rings can be moved relative to the axial direction, so they can be used as free end bearings.

Q:Cylindrical roller bearingWhat are cylindrical roller bearings, are they available in Kunshan?: The utility model is suitable for occasions where the bearing requirement is higher.

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: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:What are the components of cylindrical roller bearings?: Cylindrical roller bearings are usually guided by two blocks of a bearing ring. The cage, roller, and guide ring form a composite, generally separable bearing.

Q:Thrust cylindrical roller bearings, the main use?: Our factory uses the bearings of Changzhou Enke Bearing Co., Ltd., they have many kinds of bearings and meet various demands.
