Product Description:

Bearings four row cylindrical roller, model FC2234120


Four row cylindrical roller bearings

Four row cylindrical roller bearing is usually use in rolling mill’s work roll or back-up roll. It mainly take much radial load, which is extensively used on the work roll of wire rod mill, section mill and bloomer mill , as well as the back-up roll of dressing machine, cold rolling mill and hot rolling mill.There are three kinds of structures: FC, FCD, FCDP. There are three grades for tolerance : 0 , 6 , 5.


FC: double outer ring, single inner ring, inner ring without rid;

FCD: double outer ring, double inner ring, inner ring without rid;

FCDP:double outer ring, double inner ring, inner ring without rid



★ Product Features:

The rollers of the cylindrical roller bearing are usually guided by two flanges of a ring.

Because this assembly part composed of cage, roller and guide ring can be separated from

another ring, the cylindrical roller bearing belongs to separable bearing. This type of bearing

can be easily mounted and dismounted. Its advantages are obvious especially when there is

interference fits between the inner, outer ring and the axis, housing.

This bearing is usually subjected to radial load, only the single-row bearing with inner& outer

rings flanges can bear small steady axial load or great intermittent axial load. It has a high

requirement on the processing of the fitting parts such as axis and housing bore, etc.


Product Application: 

Cylindrical roller bearings are mainly used for:

- Iron and steel metallurgical industry

- medium and large motor

- generator

- combustion engines

- gas tuibine

- machine tool spindle

- speed reducer

- loading and unloading machinery and all kinds of industrial machinery

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 is the maximum rotational speed of a single row full cylindrical roller bearing?
FAG full cylindrical roller bearings are especially suitable for ultra high load and medium speed applications. Sealed single row and double row bearings are mainly used in transmission mechanisms, while sealed double row bearings are more suitable for lifting mechanisms. Single row full roller cylindrical roller bearings, in addition to the NJ23VH series, can not be separated. The two rings of the separable bearing can be tightly matched so that it is easy to install and disassemble.
Q:What are full cylindrical roller bearings?
Full capacity roller bearings are divided into double row full load roller, single row full roller, outer spherical roller, CARB bearingsI am a bearing manufacturer, factory direct marketing, welcome inquiry cooperation. Contact information on personal data
Q:How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?
The shoulder height (diameter) shall be smaller than the big diameter of the bearing (less than 42), mainly for easy unloading.
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: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:The Russian bearing suffix No. ZST is a cylindrical roller bearing
The suffix code is not used to distinguish the bearings, but it helps to explain the structure of the bearings and the material.
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 cylindrical roller bearings how to disassemble?
The inner ring is heated and expanded and removed rapidly; flame cutting is used directly.
Q:Thrust cylindrical roller bearings, the main use?
Thrust cylindrical roller bearings, the main use? Thrust cylindrical roller bearings are mainly used in oil rigs, iron, steel, machinery and so on.
