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:How should I find the concentricity of cylindrical roller bearings after installation?
- So, in the machining process, try to use special fixtures and parts drawing in tol and other measures to avoid such a remedy".
- Q:The thrust cylindrical roller bearings do not need the bearing seat, and the thrust bearings, shaft rings and seat rings on our unit are all in the bearing seat, often broken. The rotation of the 1. shaft in the bearing seat will not be affected, moreover, the shaft will have radial runout. 2. do not use the bearing seat, usually how to refuel?.Are there any field installation drawings or data on thrust bearings?. Thanks a million!
- Hello, I have sent a message to your mailbox, I hope you can help! Have problems you can contact us directly, Beijing Sheng Yi Huitian Electromechanical Equipment Co. Ltd
- Q:Can the Nu and N type NJ NUP cylindrical roller bearings bear axial force?
- The answer upstairs is clear. Such bearings can not be designed with axial force. In use, the inner and outer rings of the bearing can have larger axial displacement, and the aim is to compensate the length change caused by the rotating part of the two bearing due to the temperature rise.
- Q:Full use cylindrical roller bearings, uses and advantages?
- Full cylindrical roller bearings are designed to withstand heavy loads. At the same width, this kind of bearing, compared with the traditional belt cage bearing, has a very high carrying capacity, radial cross-section is small, it can save space, but the speed is relatively low.
- 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:What are the components of cylindrical roller bearings?
- Compared with the deep groove ball bearings of the same size, this kind of bearing has larger radial load capacity, and is also suitable for high-speed rotation from the structure.
- 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: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:Is the roller bearing and the bearing chamber movable in the tapered rotor motor?
- E in cylindrical roller bearing is the meaning of improving internal cage design, similar to the SKF cylindrical roller bearing EC form, this type of bearing than without E, is to strengthen the design, the roller is filled more larger to increase the load. From the load point of view, it is better to choose E.
- Q:My notes is the former has a taper hole on the cone position preload, the latter is a nut. But the online information seems a little different. Are the preload methods for two direction thrust angular contact bearings and angular contact ball bearings the same?
- The latter is mainly used as a precision screw shaft for the radial motion and axial runout requirements are very strict, generally used when they are two back-to-back, when pre tightening have strict requirements, general requirements for the radial motion and axial runout should not exceed 5 per thousand mm.
