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 2):
The bearing ring for a roller bearing according to  claim 1 ,\n wherein the compressive residual stress of the raceway surface of the first raceway portion is 250 MPa or more.
