Product Description:

Double row cylindrical roller bearings

The rollers of the double row 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.

- 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.


★ 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: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:Why does cylindrical roller bearings fail abnormally?
3, the rigidity of the shaft is poor, too large bending occurs under the load, and the span of the fixed end of the cylindrical roller bearing two is larger. When the temperature rises, the thermal elongation of the shaft causes the bending of the axle static property.4. The assembly surface falls into the hard particle or the dirt, the stress concentrates, to the open bearing pedestal when clamping, the cylindrical roller bearing ring clamp flat.
Q:Cylindrical roller and bearing outer ring processing is sheet metal forming?
Sheet metal forming? You think too simple. Do you know that a key technical parameter of a machine part is called tolerance? The inner and outer rings and roller rolling bearings (ball, roller) have strict tolerance requirements, but also requires a very high hardness and abrasion resistance, the general is the use of special alloy steel, rolling (usually hot) heat treatment after forming, after precision machining (turning, grinding etc.) after finished product.
Q:Which column roller bearing brand is good?
Foreign SKF is better, the domestic is Kazakhstan axis, and then is Taiwan's Rui Rui, you can look at yourself, they recently in the Qingdao market to great influence, you can understand.
Q:Cylindrical roller bearings N216E and N216EM after the code name is different,
You should say that the Japanese NSK bearings? NSK, N216, E stands for high load cylindrical roller bearings, N216 EM, which represents high load cylindrical roller bearings, copper alloy solid cage. E, which means strengthening the design, so the load capacity of bearings is better than without E.
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:Can the 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:Why can thrust ball bearings not sustain radial loads?
Bearing bearing axial force or radial force is determined by the structure of the bearing, thrust ball bearings are also called plane bearings, which are mainly used to bear axial force; cylindrical roller bearings can bear radial forces and are not suitable to bear axial force.
Q:NSK cylindrical roller bearings EW/EM series of differences and characteristics
E international is called "reinforced type" load, also means to increase rolling bodyW international is called a steel cage
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.
