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 6):
A roller bearing comprising:\n an inner ring comprising a raceway portion on an outer circumferential surface thereof; an outer ring comprising a raceway portion on an inner circumferential surface thereof; and a plurality of rollers disposed between the raceway portions of the inner and outer rings, wherein at least one of the inner ring and the outer ring is the bearing ring for a roller bearing according to  claim 1 .
