Sevmash, part of the United Shipbuilding Corporation (OSK), has successfully completed production and delivered to the customer the first main thrust bearing intended for the Project 22220 nuclear icebreaker "Leningrad".
The bearing was developed by the Sevmash design bureau and is accompanied by a special testing program prepared by the company's specialists. Its dimensions are impressive: the height is 2.5 meters, and the assembled weight is about 25 tons. According to the company, this is the largest industrial product in the plant's entire history.
Three such bearings are required to equip one icebreaker. The other two, intended for "Leningrad," are planned to be shipped at the beginning of 2026.
At the same time, Sevmash continues work on similar products for the next Project 22220 vessel — the nuclear icebreaker "Stalingrad." At the moment, all blanks have already been cut from metal and have passed the stage of preliminary mechanical processing. More than 20 divisions and workshops of the company are involved in the project, which highlights the scale and complexity of the production process.
