摘要： PROBLEM TO BE SOLVED: To provide a manufacturing method for a raceway member of a rolling bearing capable of assembling the raceway member even if a bolt inserting hole involves a dimensional error in the heat treatment process and capable of preventing a machining tool from being broken or the raceway member from being damaged in the turning process of the raceway after heat treatment.
SOLUTION: The diameter D of the bolt inserting hole 2e is formed to be greater than the outside diameter d of the shank part 10a of a bolt 10 by a predetermined value so that a dimensional error due to a heat treatment strain can be absorbed in the boring process, and thereby it is made practicable to assemble an outer ring 2 in a housing 52 even if a dimensional error arises in the bolt inserting hole 2e owing to the heat treatment process. Prior to the heat treatment process, an annular groove 21 is formed at each end face 2d of the outer ring 2 in its portion corresponding to the bolt inserting hole 2e so as to avoid generation of discontinuity in machining due to the bolt inserting hole 2e in the turning process of each end face 2d after heat treatment.
