Classification: CPC F  G | IPC F  G

Claim 4:
5. A bearing manufacturing method comprising:
at least one step of a method for predicting indentation resistance of a rolling bearing, a method for selecting machining conditions, and a method for selecting bearing material quality, wherein
the method for predicting indentation resistance of the rolling bearing comprising:
predicting indentation resistance of the raceway ring based on the method for measuring indentation resistance according to claim 1,

the method for selecting machining conditions uses the method for predicting indentation resistance of the rolling bearing, and the method for selecting machining conditions comprising:
based on the correlation between the area A and the indentation depth of the raceway ring, obtaining the area A, so that the indentation resistance of the raceway ring has any size, obtaining the second curve so as to form the area A, and then determining machining conditions so as to form the second curve, and

the method for selecting bearing material quality uses the method for predicting indentation resistance of a rolling bearing, and the method for selecting bearing material quality comprising:
based on the correlation between the area A and the indentation depth of the raceway ring, obtaining the area A, so that the indentation resistance of the raceway ring has any size, obtaining the first curve so as to form the area A, and then determining bearing material quality after heat treatment so as to form the first curve.
