Sevmash Advances Production of Main Thrust Bearings for Icebreaker "Stalingrad"
Sevmash, a subsidiary of the United Shipbuilding Corporation (USC), is continuing production of the main thrust bearings for the Stalingrad, the sixth serial universal icebreaker of Project 22220. One set of bearings for this vessel comprises three bearing units. Currently, two of these units have been delivered to Workshop 16 for bearing housing machining; the bearing raceways are also being machined and assembled in this workshop. The housing of the third unit is being assembled in the plant's hull welding shop. Meanwhile, in a dedicated area of Sevmash Workshop 4, bearing internal filling operations are underway, including the manufacture of bushings and bearing housings with anti-friction layers and filling with hot Babbitt metal. Each unit requires the installation of 24 bearing housings. This stage is one of the most labor-intensive processes in bearing manufacturing.
