1. Bearing materials

 

The influence of metallurgical quality of bearing material is the main factor of early failure of rolling bearing. With the progress of metallurgical technology (such as bearing steel, vacuum degassing, etc.), improve the quality of raw materials. The proportion of raw material quality factor in bearing failure analysis has decreased obviously, but it is still one of the main factors of bearing failure. Whether the selection is appropriate is still the bearing fault analysis must be considered.

 

2, processing

 

Bearing manufacturing will go through a multi-step operation of forging, heat treatment, turning, grinding and assembly. The rationality, advancement and stability of the treatment will also affect the service life of bearings. The influence of bearing heat treatment and grinding process, often has a more direct relationship with bearing failure related to product quality.

 

3, transportation,
In addition to the factors that affect the quality of bearings, including the production of raw materials and the production process, there is a more important problem, that is the transportation of bearings. Some bearings need long-distance transportation to complete the production of agents or customers. There are many uncertain factors in the transportation process, and the quality of bearings may be affected without attention.
