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.
