Product Description:

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


Bearings single row cylindrical roller, model NU203


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:Why should the main shaft be coupled with double row cylindrical roller bearings?
Because double row cylindrical roller bearings with high carrying capacity, high precision, separation, easy installation and disassembly, mainly used in lathes, milling machines, machining centers and other high-precision machine tool spindle. Hope to be of help to you.
Q:Cylindrical roller bearings, mounting dimensions, specific meaning? Twenty
I don't know what you mean. The size of NUP2311E is: inside diameter, 55mm, outside diameter, 120mm height: 43
Q:Does the thrust cylindrical roller bearing need a bearing seat?. Five
In general, this kind of bearing does not use the bearing seat
Q:What does "cylindrical roller bearing" ENV mean?
Cylindrical roller bearings, the basic model suffix ENV meaning:E: enhanced design with improved bearing load capacityN: the outer ring of the bearing is provided with a stopping grooveV: full installed roller (no 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.
Q:For bearing type, no outer ring single row cylindrical roller bearings, bore 40, thickness 21, roller diameter 8, roller length 12
Specific circumstances need to be further confirmed with your drawings.Reminder: please buy the product specifications and product quality guarantee, so as not to buy fake and inferior bearing products.Handmade, thank you for your adoption, and if you have any questions, please continue to ask.
Q:Full use cylindrical roller bearings, uses and advantages?
Otherwise, due to lack of lubrication and high-speed operation will cause more wear and tear. I am a bearing
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:KOYO cylindrical roller bearings, //KOYO cylindrical roller bearings, how to determine the accuracy level?
The allowable deviation of 1, the inner and outer diameter, width and the width of the assembly allowable deviation 2, roller diameter and the outer round round in group 3, the diameter of the chamfer size bounds value 4, the width of the allowable rotation accuracy (momentum and rotating body beating related projects) 1, inner ring and the outer ring allows for radial and axial beating 2, inner ring 3, allowing the lateral runout of outer surface inclination to allow changes in volume 4, the thickness of the thrust bearing raceway permissible variation
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.
