ABSTRACT:
An antifriction hearing race, particularly for highly stressed antifriction bearings in aircraft power units, which have a fixed joining of two layers made of different metallic materials, with an area of the raceways for the roller bodies being made of a steel with a very high degree of hardness and resistance to wear, and the core area of the antifriction bearing race being made of a high-strength steel. A powder-metallurgical high-speed steel has a high content of carbide-forming alloying elements and a high carbon content is provided as the material for the raceway of the roller bodies, whereas the material for the core area of the antifriction bearing race is made of a hot-work steel with, in comparison to the raceway material, a lower content of carbide-forming alloying elements and with a low carbon content, both materials being joined to one another with material fit by diffusion welding.
