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: What are the differences between cylindrical roller bearings nu208m and nu208em?
E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!
Q: Cylindrical roller bearings NUP2311E mounting dimensions: Da (max): 69Da (min): 64DB (min): 72DC (min): 80Da (max): 111What are the specific meanings of these dimensions? Thank you, master
Da means shoulder diameter, that is to say, the maximum shoulder size is 69mm, and the minimum is 64mm
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: What's the difference between imported bearings and imported bearings?
Domestic bearings used in the cage and rivet and washer, spacer ring, sealing ring, pillar, pin etc. the material is divided into black metal materials (such as low carbon steel, stainless steel etc.), non-ferrous metal materials (such as brass, bronze and Aluminum Alloy etc.) and non metal materials (such as plastics, phenolic textolite three) etc..Imported bearings are basically the same as those made in China. There are copper, steel, alloy and so on.
Q: What kind of material is used for cylindrical roller bearings?
Ah, you ask what material to do, of course, with the bearing steel do ah. Bearing steel, however, is well distributed. Generally use GL15#
Q: Why are there no double row cylindrical roller bearings in the mechanical design manual?
So under normal circumstances, the bearing bore and the shaft is no gap.But do you mean that the inner ring and the shaft of the bearing are fixed,
Q: Can it be used for axial alignment? Forty-fiveWhat is the function of the flat retaining ring of NUP cylindrical roller bearings with flat retaining rings? Can it be used for axial alignment?How much axial force can I bear then?You are the ZWZ? Can you make a friend?!How much axial force can you bear? Do you have a formula or a recommended value?NUP is needle roller bearings, brothers, I dialed the wrong number:What is the function of the flat retaining ring of the needle roller bearing with flat ring NUP? Can it be used for axial alignment?There seems to be no experts here, all mixed up
Yes, the function of the flat ring is to bear the axial force and be used for axial positioning.
Q: How to calculate the clearance of bearings, such as 23226 double row cylindrical roller bearings
First of all for the bearing clearance calculation is a very complicated problem, because the bearing structure of different types, and the usage of different materials, the temperature of different factors such as the clearance is different, and because of the different structure types and some bearing bearing clearance is divided into radial clearance and axial clearance; also need to pay attention to the bearing clearance is usually divided into the following 1. conditions, clearance before installation, usually refers to the bearing manufacturers factory according to the standard to determine the clearance of bearing clearance. 2., after the installation clearance, because the bearing inner ring and the shaft is interference fit, when the bearings installed on the shaft, its inner ring will be as the amount of interference and expansion, resulting in smaller clearance of bearings. 3. clearance work, because the bearing is affected by load and rotating friction in the work, the temperature will gradually increase, will cause the bearing inner ring further expansion, which will make further changes in bearing clearance. However, the main clearance of the bearing is the largest (minimum) diameter of the raceway of the outer race of the bearing, the largest (minimum) diameter of the rolling body and the largest (smallest) diameter of the raceway of the inner race. For example, cylindrical roller bearings, its largest clearance = outer raceway raceway, maximum diameter of -2* roller minimum diameter - inner raceway minimum diameter derived, and conversely, for the smallest clearance. The average user of bearings actually doesn't need to know that.The other 23226 models should be the spherical roller bearing, not double row cylindrical roller bearing.I hope my answer will be of some help to you!
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. Our factory uses the bearings of Changzhou Enke Bearing Co., Ltd., they have many kinds of bearings and meet various demands.
Q: Why should the main shaft be coupled with double row cylindrical roller bearings?
Separable, easy to install and disassemble, mainly used in lathe, milling machine, machining center and other high-precision machine tool spindle. Hope to be of help to you.
