Reasons for Fracture and Failure of Stainless Steel Bearings

The main reasons for the fracture and failure of stainless steel bearings are defects and overload. When the external load exceeds the material strength limit and causes part fracture, it is called overload fracture. The main cause of overload is sudden failure or improper installation of the host. Defects such as microcracks, shrinkage cavities, bubbles, large foreign objects, overheated tissues, and local burns in bearing parts can also cause fracture at the defect site during impact overload or severe vibration, which is called defect fracture. It should be pointed out that during the manufacturing process of bearings, the re inspection of raw materials, quality control of forging and heat treatment, and processing control can be accurately analyzed through instruments to determine whether the above defects exist. In the future, it is still necessary to strengthen control. But generally speaking, most of the commonly occurring stainless steel bearing fracture failures are overload failures.
