Factors of INA roller bearing failure

INA roller bearings failure mainly was caused by defects and overload coefficient two factors. The most common is the external load exceeds the material ultimate strength caused parts damage and overload fracture.

Overload is the main reason of improper installation or host suddenly break down. Under normal circumstances, INA needle roller bearings parts micro crack, shrinkage, bubbles, large foreign body, burns and other local organizations and severe shock or vibration overload overheating defects can lead to fractures of the defect, which we call the defect fractures.

Therefore, in the manufacturing process,we need strict raw materials inspection, a good pass. Further control on forging and heat treatment quality, control equipment processing, this can correct analysis of these defects. But in general, INA bearing failure occuring caused overload fault.
