Product Specifications:

cylindrical roller bearing , Cylindrical roller and race for line contact bearing. Load capacity is big, mainly bear radial load .

1. Friction coefficient is small, suitable for high speed limit speed close to deep groove ball bearings

2.N and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing

3. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contact stress concentration

4. Inner ring or outer ring separable, easy to install and remove

Product Applications:

Cylindrical Roller Bearing Application Flied:Rolling Mills,Crusher,Mining

Metallurgy Petroleum,Chemical Industry,Engineering Machinery,Port,Oil,Gas,

Wind,Agriculture,Lathe,CNC,Steel Works,Electrical Machinery,Axle/Limber,

Tractor,Autocar,Crude Oil Engine and so on.

NJ 204 E,Cylindrical Roller Bearing Used Mower Wheels Bearings

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 you make it clear? I don't understand. Thank you for being here first.: Oh, My God！！！ Do you understand the bearings in this way?! What is called "roller" means that the rolling column is cylindrical and similar to cylindrical shape, such as short cylindrical, long cylindrical, tapered roller, spherical roller, etc.." This kind of statement should be listed as the promotion answer!!! Absurd! Laughable! !!The standard answer is: Bearings in accordance with the direction of force, divided into radial bearings and thrust bearings, in simple terms, if the main force to bear the axial thrust bearings, thrust bearings; otherwise, that is, radial bearings. As for radial roller bearings, simply speaking, it is the roller bearings that mainly bear radial forces. It's so simple, there's so much nonsense!!!

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.

Q:In the car there is a cylindrical roller, the size of the diameter of 25mm, the outer diameter of 32mm, width of 9.5mm, who knows what the standard size, have direct purchase Mody, thank you!: 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: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:How much is the shaft shoulder height of the 81105 cylindrical roller bearings with inner diameter 25mm?: The purpose of the shoulder shaft is to limit the axial sliding, of course, as the thrust bearing, the main bearing capacity is the axial force, so the shaft shoulder size can be appropriately larger.

Q:How are the twin row cylindrical roller bearings classified?: Classification of double row cylindrical roller bearings:The NN0000 type cylindrical roller bearingsThe bearings are compact in structure and small in deformation under load, so they are especially suitable for the support of the spindle of machine tools. Because of its no outer wall, so you can install the outer ring and the inner ring assembly respectively (with roller and cage), does not limit the axial displacement of the shaft or housing, compared with the single row cylindrical roller bearing with the same radial size, can bear larger radial load.

Q:What are the differences between cylindrical roller bearings nu208m and nu208em?: E means "reinforced", "rolling", "thickening", "change", "change".. Hope to adopt!!

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.
