Method for hardening at least one raceway (2, 2a) of a bearing ring for a large-diameter anti-friction bearing, comprising the following method steps: - arranging of at least two main inductors (3, 4) in the region of a common starting zone of the raceway (2, 2a), and heating of the raceway (2, 2a) in the region of the starting zone by means of the main inductors (3, 4); - moving of the main inductors (3, 4) in opposite directions along the raceway (2, 2a), and heating of the raceway (2, 2a) by means of the inductors (3, 4) in intermediate zones which are passed by the latter consecutively, until a zone is reached and heated, at which zone two main inductors (3, 4) which are moved in opposite directions meet with the formation of a common end zone; - using of an additional auxiliary inductor in the region of the end zone, preheating of the raceway (2, 2a) by way of the auxiliary inductor in the region of the end zone, and removing of the auxiliary inductor from the region of the end zone before the two main inductors (3, 4) approach the end zone directly; - quenching of the raceway (2, 2a) in the region of the starting, intermediate and end zone/zones (8, 9, 10) which are heated by means of the inductors (3, 4, 11), and - homogenizing of the heating of the raceway (2, 2a) in the region of the common starting and/or end zone (8, 10) by way of at least one additional measure, characterized in that - the additional measure provides mechanical controlling or setting of at least one selected property of the auxiliary inductor at least during the preheating of the end zone, - the at least one selected property being the locality of the auxiliary inductor, and the additional measure providing a movement of the auxiliary inductor during the preheating, which movement takes place with at least one additional degree of freedom. - arranging of at least two main inductors (3, 4) in the region of a common starting zone of the raceway (2, 2a), and heating of the raceway (2, 2a) in the region of the starting zone by means of the main inductors (3, 4); - moving of the main inductors (3, 4) in opposite directions along the raceway (2, 2a), and heating of the raceway (2, 2a) by means of the inductors (3, 4) in intermediate zones which are passed by the latter consecutively, until a zone is reached and heated, at which zone two main inductors (3, 4) which are moved in opposite directions meet with the formation of a common end zone; - using of an additional auxiliary inductor in the region of the end zone, preheating of the raceway (2, 2a) by way of the auxiliary inductor in the region of the end zone, and removing of the auxiliary inductor from the region of the end zone before the two main inductors (3, 4) approach the end zone directly; - quenching of the raceway (2, 2a) in the region of the starting, intermediate and end zone/zones (8, 9, 10) which are heated by means of the inductors (3, 4, 11), and - homogenizing of the heating of the raceway (2, 2a) in the region of the common starting and/or end zone (8, 10) by way of at least one additional measure, characterized in that - the additional measure provides mechanical controlling or setting of at least one selected property of the auxiliary inductor at least during the preheating of the end zone, - the at least one selected property being the locality of the auxiliary inductor, and the additional measure providing a movement of the auxiliary inductor during the preheating, which movement takes place with at least one additional degree of freedom.
