FIELD: machine building. ^ SUBSTANCE: procedure for preparation of rotating element for longer service life of bearing consists in: application of metal material on surface of rotating element orthogonally to lengthwise axis of rotating element, also, contents of chromium in material is less, than contents of chromium in rotating element. Further, the procedure consists in treatment of surface of metal material orthogonal to axis of the rotating element. The rotating element increasing service life of the bearing consists of: the rotating element; surface of metal material orthogonal to lengthwise axis of the rotating element with contents of chromium, less than the rotating element; a boundary layer between surface of metal material and the rotating element orthogonal to lengthwise axis of the rotating element; also, surface of metal material corresponds to supporting surface taking axial load; surface of metal material has contents of chromium below 2.2 percents. ^ EFFECT: increased service life of bearing; finished supporting surface eliminates problems of fluffiness. ^ 10 cl, 4 dwg |
