The article presents the main causes of wear on the seats of rolling bearings during operation, which are fretting corrosion and turning of the inner and outer rings of bearings. Installed that an effective way to protect metal surfaces from fretting corrosion is to place an intermediate medium between them. Coatings with a small modulus of elasticity are applied to one or both contacting surfaces to create an intermediate medium. Using anaerobic sealants as coatings with a small modulus of elasticity is recommended. Anaerobic sealants, which are multicomponent liquid compositions capable of remaining in the initial state for a long time without changing properties, quickly cure at temperatures of 20-25° C and in case of violation of contact with oxygen in the air with the formation of a durable solid polymer. The application technology of anaerobic sealants is presented, and the influence of temperature, talc, and copper on the physical and mechanical properties affecting the durability of fixed joints is studied. According to the results obtained, using the AN-6K and AN-103 brands of anaerobic sealants is recommended as the most effective for restoring fixed joints of rolling bearings and increasing their durability. The article substantiates the influence of temperature and various fillers on the physical and mechanical properties of anaerobic sealants; based on these results, the brands of sealants suitable for restoring fixed joints from rolling bearings are recommended.
