description: The given work is devoted to the influence of the properties and characteristics of the structure of 8Cr4W9MoV2 material on the operational characteristics of rolling bearings for aviation application and search for possible technological solutions for their improvement. The research sets the following goals: 1. Analysis of the causes of damage to rolling bearings. 2. A study of the influence of residual stresses on the operating durability. 3. Study of the effect of hydrogen amount on the operating durability. 4. Fractographic researches of revealed cracks. 5. The study of the microstructure of rolling bearings. 6. Search for modern ways to improve the operating durability of the considered rolling bearings. This paper presents the results of researches of an influence of production factors on the performance of the bearings operating under increased pressures and temperatures. There are the estimations of the influence of different factors on the operational durability in this paper. A study of the microstructure and fractures of the steel was carried out. The result of the research shows that the main factors having a significant impact on the operational durability are the magnitude of the compressive stress, the content of total and diffusion-movable hydrogen. The solutions to prevent the damage of the rolling bearings have been suggested.
