Abstract: Bearings installed on the shaft of the trawl winch drum are one of the most loaded and critical structural elements. They provide rotation of the drum, perceive significant radial and axial loads arising during setting and sampling of the trawl. The reliability of the bearing assemblies directly affects the uptime of the entire winch, the productivity of the field and the cost of maintenance. This article discusses the main aspects of reliability of bearing assemblies, factors affecting their performance, determination of the load acting on the bearing assembly. The non-stationary nature of the load is determined by many factors, including the hydrodynamic resistance of the trawl during its movement in the aquatic environment, the change in the trawling depth, the uneven filling of the trawl with fishing objects, the effect of sea waves on the vessel, as well as the maneuvering of the vessel during trawling. These factors create a complex range of variable loads affecting the bearing assemblies of the trawl winch drum.
