Product Description:

NU style with double outerrid, and the outer ring, roller,cage can separate from the inner ring.


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:Is the nu240em cylindrical roller bearing split?
Therefore, such bearings need to be installed in the axial load bearing the main components, only at the same time using other types of bearings to withstand axial load on the premise that can be used.
Q:How should I find the concentricity of cylindrical roller bearings after installation?
Any form of assembly, adjustment center is a very troublesome thing, but also in the measuring installation is not very complete, the usual method is to in the base below (or below) thin copper with different thickness, until you feel better, but each installation to re adjust.
Q:How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings
1, radial clearance: non preload, bearing radial load, the radial clearance of G for any angle along the radial direction, in the absence of external load relative to the outer ring inner ring from a radial eccentric limit position, move to the opposite limit position of the radial distance arithmetic mean.2, axial clearance: non preload, bearing can withstand axial load in two directions, the axial internal clearance of G: without external load, a ring relative to the other ring, from an axial limit position toward the average axial distance limit position opposite the.
Q:Deep groove ball bearings 6120, self-aligning ball bearings 1210,
The cylindrical roller bearings are in line contact with the outer ring of the bearing, and have the largest contact surface with the outer ring of the bearing. And the large contact surface means that in the same radial force, the same speed, friction, and thus generate more heat, and thus affect the life.
Q:Cylindrical roller bearings standard 10
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:What is called a semi convex roller, a fully convex roller, a logarithmic curve roller?
The logarithmic curve roller is also a convex roller, which belongs to a full convex roller;The shape roller refers to a roller which has a slight modification to the diameter of the outer end of the roller to prevent the stress concentration at the end of the contact between the roller and the raceway.The corresponding types of bearings are cylindrical roller bearings and tapered roller bearings. Modified roller and convex roller have been widely used in domestic roller bearings, which can improve the service life of the products.
Q:For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12
This is the outer ring and the inner ring can be separated, the bearings in the country can be produced, imported bearings are sold.Another model is up to your standard,Cylindrical roller bearings SL183008Semi position bearing, full cylindrical roller, dimension series 30M 0,31 kgqualityCr 66000, NBasic rated dynamic load, radialC0r 67000, NBasic rated static load radialCur 11200, NFatigue limit load, radialNG 6300, 1/minLimit speedNB 4300, 1/minReference speed
Q:Can cylindrical roller bearings bear high temperature?
A class of grease, temperature is not more than 120 degrees, and then high temperature will lose lubrication performance, leading to the bearings can not work, in fact, bearing itself can withstand high temperature.
Q:Does the use of cylindrical roller bearings reduce the limit speed?
Rolling bearing face to face or back to back, the speed limit will be reduced? Yes, especially in order to obtain a large preload or a large gap of the matching. Cylindrical roller bearings in pairs, the limit speed will be reduced? Cylindrical roller bearings do not exist in pairs, one said that you can use the same internal and external diameter of double row, four column cylindrical bearings, the same internal and external diameter of double row, four column bearings, compared to single row cylindrical bearings limit speed will be reduced
Q:Double row cylindrical roller bearings how to disassemble?
If it is replaced, use the flame to heat it quickly under the conditions permitted!
