Precautions for fag cylindrical roller bearing burn

• The second may be excessive load (excessive preloading). Excessive speed. The clearance is too small. Intrusion of water or other foreign matters. If neither of the above two cases is true, the accuracy of the shaft and bearing housing is poor and the deflection of the shaft is large. 
• Seeing this, I think everyone wants to know the solution. First of all, we should study the lubricant and lubrication method, select the right bearing lubricant and its dosage, and correct the choice of bearing. The clearance and preloading of cylindrical roller bearing should be studied, and the sealing device should be improved. Check the accuracy of the shaft and bearing housing.
• According to the inspection results, if the cylindrical roller bearing is found to be damaged or abnormal, please find out the causes and formulate countermeasures according to the phenomenon of bearing damage. If some cylindrical bearings have defects, they can’t be replaced with new ones.

Precautions for fag cylindrical roller bearing burn

• Any one of the inner and outer rings, rolling elements and cage has cracks and fragments.
• Any one of the inner and outer rings and rolling elements has peeling.
• The raceway surface, retaining edge and rolling element are significantly jammed.
• The cage is seriously worn or the rivets are loose.Precautions for fag cylindrical roller bearing burn
• The raceway surface and rolling element are rusty and scarred.
• The rolling surface and rolling body have significant indentation and indentation.
• There is creep on the inner diameter surface of the inner ring or the outer diameter of the outer ring.
• Overheated and discolored.Precautions for fag cylindrical roller bearing burn
• The seal ring and dust cover of grease sealed bearing are damaged seriously.Precautions for fag cylindrical roller bearing burn
• In terms of the long duration of rolling bearing rotation, FAG bearing rotation lasts a long time, stops slowly and has good flexibility. On the contrary, if the rotation time is short and the stop is sudden, the flexibility is not good. 
• It is not easy to measure the radial clearance of the rolling bearing from the aspect of the radial clearance of the fag bearing, because the measuring force will cause the elastic deformation of the ring of the rolling bearing, the rolling body itself and its contact.
• In terms of the structure and size of fag bearing, due to the different structural types and sizes of rolling bearing, there should be different requirements for its rotation flexibility. For example, single row centripetal ball bearings and single row centripetal thrust ball bearings.
• These fag bearings are relatively light when rotating due to the small contact area between the rolling element and the ferrule, while double row centripetal spherical bearings and thrust roller bearings, due to the large contact area between the rolling element and the raceway and the small weight of the outer ring, although a certain load is added when checking their rotation flexibility, their lightness is still not as good as that of single row centripetal ball bearings.Precautions for fag cylindrical roller bearing burn
