Abstract
An apparatus for hardening cylindrical bearing faces (L) of a shaft (K), wherein at least one of the transitional radii (R , R ) to the adjoining shaft portions (W , W ) is constructed recessed, includes a pair of inductive heating units ( ), which are each formed at least by one inductor ( ) having two spaced-out heating conductor branches ( ); an adjusting device ( ) for adjusting the inductors ( ) simultaneously from the radial direction (R) on to the bearing face (L) to be hardened and a second adjusting device ( ) for moving at least the inductor ( ) associated with the recessed radius R , R ) after application to the bearing face (L) by a movement directed axis-parallel with the longitudinal axis (X) of the shaft (K) in the direction of the recessed transitional radius (R , R ) until its outer heating conductor branch ( ) has moved into the particular transitional radius (R , R ).
