However, modern, high quality bearings can exceed by a considerable margin the values calculated for the basic rating life under favourable operating conditions. Ioannides and Harris have developed a further model of fatigue in rolling contact that expands on the Palmgren theory and gives a better description of the performance capability of modern bearings. 

  

The method "Expanded calculation of the adjusted rating life" takes account of the following influences: 

  

the bearing load 

the fatigue limit of the material 

the extent to which the surfaces are separated by the lubricant 

the cleanliness in the lubrication gap 

additives in the lubricant 

the internal load distribution and frictional conditions in the bearing.

The influencing factors, especially those relating to contamination, are extremely complex. A great deal of experience is essential for an accurate assessment. As a result the Engineering Service of Nanjing Haning Bearing Manufacturing Co., Ltd Industrial should be consulted for further advice.

Faults of Rolling bearing:

1. The bearing temperature is too high .

When the bearing works , installation position can have  a certain temperature . When you touch its shell,   it won ' t be too hot , otherwise it indicates that the bearing temperature is too high. The following is the reason:
