Specification of Cylindrical roller bearings:
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
Single row cylindrical roller bearings
- NU, N single row cylindrical roller beaings
NU type and N type allows axis relative the cage within the scope of certain to do axial movement, it would adapt for thermal expansion or installation error caused by the shaft and housing relative position changes, they suit to use for free end bearing. Because they can not limit shaft and the shell axial displacement, and can only bear the radial load.
- NJ, NF single row cylindrical roller bearings
Both NJ and NF can bearing single direction axial load in a certain extent.
- 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.
- NCL…V single row cylindrical roller bearings
No outer rim but with double lock ring without cage cylindrical roller bearing.
The bearing no cage, roller number is more, and size of the same other cylindrical roller bearing is able to withstand the big radial direction load, but its limit rotational speed is low. The bearing inner ring and outer inseparable, cannot install respectively, can limit shaft or housing of the two directions of the axial displacement in bearing axial clearance within the limit.

- 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:Can you make it clear? I don't understand. Thank you for being here first.
- A rolling body is a short cylinder.The inner ring (or outer ring) of the bearing can be split.
- Q:How to check the thrust cylindrical roller bearings?
- Bearing dimensions (or bearing samples) have "basic rated load (KN)", this column can be directly detected, in general, according to the use of appropriate multiplied by a (1.2~1.5) safety factor. In accordance with the requirements of the design manual, the equivalent load can be calculated (considering the speed, temperature, load and stability).
- Q:Full use roller bearings
- The service is applied to all axle box bearings, including FAG cylindrical roller bearings, spherical bearings and tapered roller NSK bearings. In addition, FAG industry services also provide support to customers in the rail industry who introduce maintenance management systems. INA bearing agent Chinese by helping clients improve internal maintenance procedures, F IS can enhance the data exchange between various departments, and clearly useless procedures, such as entry in IT system and database in different kinds of data. This reduces the cost of raw material management and speeds up maintenance activities. NSK it is very important for the effective maintenance management to install the bearing units rapidly and effectively in china. At the same time, the F IS offers a range of energy saving bearing heaters. Including the FAG Powertimken series induction heater, to enable customers to reduce the installation time of bearing, NSK bearings so as to shorten the downtime, instead of using the traditional heating method (oil bath heating stove, or board). FAG is a research and development partner and supplier of the world's leading Boeing 787 manufacturer. The quality, reliability and efficiency of Schaeffler's aviation bearings, INA bearings, price fits, and performance in extreme conditions, the INA bearing agent provides support for the international space navigation corporation. FAG's bearing technology is used on almost all modern aircraft.
- Q:Cylindrical roller and bearing outer ring processing is sheet metal forming?
- Rolling bearings are made by special bearing factories and manufactured by precision special machine tools. It is a highly specialized field in mechanical manufacture. Precision bearings are the key parts to determine the accuracy and operation of the machine. At present, China mainly relies on imports (such as Japan NSK bearings) in high precision bearings.
- 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 single row full cylindrical roller bearingsFAG single row full cylindrical roller bearings can bear large radial loads, and can also bear single direction axial load. Axial positioning can be guaranteed by a symmetrical arrangement of similar bearings. NCF, 29V, NCF, 30V series of bearings have two fixed inner ring, the outer ring has a baffle, they can only bear the direction of the outer edge of the fixed axial load. The NJ23VH series bearings can bear the axial load toward the inside of the inner ring, and their rollers are fixed in the outer ring, even if the inner ring is taken away. The two rings are tight fit, easy installation and disassembly.
- Q:Double row cylindrical roller bearings how to disassemble?
- The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.
- 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?
- 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. 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.
