Why 6204 bearing failure

As we know,6204 bearing is single row deep groove ball bearings,its the most widely used in many 
applications,6204 bearing inner diameter is 20mm,outer diameter of 6204 bearing is 47mm,width of 6204 is 14mm,the weight is 6204 bearing is 0.11kg,the material we adopt high quality chrome steel,ABEC-1 6204 Bearing and ABEC-3 6204 bearing are available in our stock.XRB(China bearing manufacturer) also supply rubber sealed single deep groove ball bearing 6204-2RS and metal shield 6204-ZZ Bearing.
 
The user usually found the 6204 bearing failure when the bearing operation,but why that's happened,XRB customers always ask this question,now let me explain why the 6204 bearing failure.
 
1.6204 bearing burning:burned 6204 bearing have the Tempering Colour on the raceway or rolling element,maybe less lubrication or bad lubrication oil cause this,of course maybe the tight fitting of the 6204 bearing.
 
2.Plastic Deformation:there are some Uneven pits on the surface between raceway and rollers of 6204 bearing,it because 6204 bearing occured plastic deformation,the reason is large static load or impact load of 6204 bearing,working load exceed the material yield limited load.
 
3.Crack of the 6204 bearing ring:tight fitting of 6204 bearing,the loose of the 6204 bearing inner ring or outer ring,worse quality of 6204 bearing cage.
 
4.Cage fragmentation:because of insufficient lubrication of 6204 bearing,rolling element broken.
 
5.Dusty entry makes the broken of the raceway of 6204 bearing,or less lubration and improper lubration oil.
 
XRB can supply 6204 bearing the right quality with best price,save your purchase cost. so please tell us your applications and more requirement about our 6204 bearing,thanks.

How to manufacture high quality sealed spherical roller bearings

First step:the forging of sealed spherical roller bearings
 
The rings of sealed spherical roller bearings adopt forging technical process,forging can make the workpiece of metal distributed streamline.increasing material density of the rings of sealed spherical roller bearings,and the service life of sealed spherical roller bearings can be increased by 2 to 5times.
 
Second:lathe machine processing 

XRB(China bearing manufacturer) adopt CNC Lathe machine to process the ring of sealed spherical roller bearings,control the size and deformation of the ring strictly.Provide a good foundation for subsequent processing.
 
Third: heat treatment of sealed spherical roller bearings 

the quality level of heat treatment is very important for the quality of bearings,that is the technical gap 
with Japan and Germany quality,XRB have heat treatment equipment which are adopted advanced roller mesh belt type controlled atmosphere continuous production equipment, there are 5 temperature points when quenching and tempering,the temperature can be controlled precisely.its better for internal organizational structure of sealed spherical roller bearings ring,increased low cleaning technology when processing.reduce internal residual austenite of sealed spherical roller bearings ring,improve organizational stablity during storage and operation.
 
Fourth:Grinding process of sealed spherical roller bearings
 
1.all of XRB sealed spherical roller bearings are processed by high precision CNC grinding equipment,high precision machining,high degree of automation,high product consistency,and long service life.
2.Grinding production perform high control requirements of internal standards
3.Grinding process inspection including the first article inspection,process inspection and completion inspection.
 
Sealed spherical roller bearings can be used in heavy load application,XRB quality is the similar with Japan standard,but competitive price,welcome discuss for details.

Related bearing:SKF 22216E bearing,SKF bearing 22216E,22216CC/W33,22216 BEARING bearing size SKF spherical roller bearing 22216 dimension bearing inner diameter 80mm bearing outer diameter 140mm bearing width 33mm CXRB BEARING is 22216 china bearing manufacturer, factory,supplier and exporter, we focus on produce spherical roller bearing 22216,The design (cage)of spherical roller bearing :CAK/W33,E,E1,EAE4,CC/W33,EAS.M,C,MB/W33,BS 22216 bearing design and applincation 22216 Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis. The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection. Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions. 22216 bearings are widely used in Papermaking machinery, railway vehicle axle, rolling mill, roller gearbox, crusher,vibrating screen, printing machinery,woodworking machinery,industrial reducer,mine.and 22216 bearing are popular size that could be used in many applications.
