Abstract: The invention relates to methods for testing a bearing component, in order to ensure that the bearing surface and a load-bearing region located underneath said bearing surface are in a perfect condition. According to the invention, a material testing depth containing the point of maximum mechanical load during operation is determined; in a first partial testing step, the bearing component is subjected to an ultrasound test by which means the material region underneath the bearing surface is tested for defects by means of ultrasound, at least up to the material testing depth; in a second partial testing step, a full optical test of the bearing surface is carried out, during which the actual surface state of the bearing surface is compared with a nominal surface state; and the bearing component is then only classified as faultless if the results of the two partial testing steps do not reveal any defects.

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.

Abstract: The invention relates to a roller bearing comprising a roller bearing ring. In order to produce a roller bearing that has a high rotational speed value and operational load using minimum quantity lubrication and in which the heat produced in the bearing can be removed in a rapid and reliable manner, the roller bearing ring is made of a material composite. The first material composite component forms the running surface and is made of a refractory metal or a sintering material, the thermal conductivity and heat resistance thereof being higher than the thermal conductivity and heat resistance of the at least one additional material composite component which forms the base body of the roller bearing ring.
