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:What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
- What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?Semi convex, convex roller is in plane roller axis, the outer surface of a continuous or discontinuous convex curved basic cylindrical or conical roller, to prevent the end of the roller and raceway contact stress concentration. The roller is generally defined as a convex roller and a modified roller.
- 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: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!
- There is some doubt about your description. According to your internal diameter and external diameter, if the cylindrical roller bearings, the scroll is quite small. I don't see much of this kind of cylindrical roller bearing. Do you mean needle roller bearings? If needle roller bearings can be found, and HK2514/18 RS similar models.
- 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: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!
- In general, this kind of bearing does not use the bearing seat
- 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 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: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?
- Dissimilarity! The former is mainly used as the support of the shaft with larger load. The main prevention is the radial runout, which is usually used individually, so there is not much demand for the preload.
- Q:For example, NU, NJ, N, RNU, NUP, NF, NO, NN, RN, what do you mean, who can tell me about that hero?
- NN double row cylindrical roller bearing inner ring gear side no outer wallRN no outer ring type N cylindrical roller bearing
- 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.
