Key factors of stainless steel bearing fracture failure

 

The key factors causing cracking failure of stainless steel bearings are defects and overload. When the load exceeds the material bearing limit, it will cause parts cracking failure.

 

Stainless steel bearing has the large foreign impurities in the operation process, crack, shrinkage cavity, bubbles, local burn out and defect problems such as overheated organizations, it is easy to cause in the process of actual operation impact overload cause its cracking failure, also have the defects of bearing will cause cracking because of the vibration of the work, this is defective craze.

 

When manufacturers are in the process of manufacturing stainless steel bearings, they generally carry out inspection, forging and heat treatment of raw materials, effectively control the quality, and try to avoid defects through a series of technological processes.

 

Therefore, under normal circumstances, the current stainless steel bearing cracking failure, most of the overload failure.

 

Stainless steel bearings have excellent performance, because its process is more strict, the material itself also has good characteristics, but because of the use of the environment, often need to carry out lubrication.

 

But because the lubricating oil will continue to oxidation in the air, and produce acid substances, which will cause bearing corrosion, so in stainless steel bearings need to pay attention to the corrosion resistance of the material.

 

In order to better reduce the cracking failure caused by overload of stainless steel bearings, it is necessary to ensure that the multi-choice of materials have the corresponding wear resistance and fatigue resistance. Because bearings need long-term operation, if there is no good wear resistance and fatigue resistance, it will not be long before the failure and cracking.
