Abstract:
A bearing ring for a roller bearing includes: an inner layer part that is formed of tempering martensite or sorbite; and a surface layer part that surrounds the entire periphery of the inner layer part, in which Vickers hardness of a surface thereof is larger than that of the inner layer, and which is formed of tempering martensite. A raceway portion of the surface layer part a portion that is in contact with at least one end of the rolling contact surface of the roller in an axial direction, and includes a first raceway portion at which compressive residual stress of the raceway surface is relatively high.

Claim (Index 4):
A method for manufacturing a bearing ring for a roller bearing, the bearing ring for a roller bearing according to  claim 1 , the method comprising:\n (A) a process of performing quenching treatment on an annular workpiece formed of high carbon chromium bearing steel; (B) a process of performing tempering treatment on the workpiece on which the quenching treatment has been performed, and immersing the entire workpiece in a cooling liquid, and heating the workpiece in this state; and (C) a process of performing a finishing process on the workpiece on which the tempering treatment has been performed, wherein the process (B) is performed in a state in which a flow of the cooling liquid is generated in the cooling liquid in which the workpiece on which the quenching treatment has been performed is immersed such that the cooling liquid is concentrated on a portion at which the first raceway portion of the workpiece is formed.
