The Russian defense industrial enterprise Sevmash will manufacture a set of main thrust sliding bearings for the propeller shafts of the sixth serial universal icebreaker of Project 22220 "Stalingrad". This was reported by the developer's press service.
The set for one vessel consists of 3 bearings. The first product has already been sent to mechanical workshop No. 16, where the body will be machined to drawing dimensions, and the bearing cage will be manufactured and assembled.
After machining, it will be sent for final assembly. Then the product will be transferred to the Baltic Shipyard.
The bodies of 2 more bearings are being assembled in the enterprise's hull-welding production. Work is underway in workshop No. 4 to internally fill the products. This involves the manufacture of liners and pads with an anti-friction layer.
It is planned that the set of bearings will be manufactured in 2027. The enterprise emphasized that the work is proceeding according to schedule.
The design documentation for the support elements was developed in the Sevmash Design Bureau according to the customer's technical specifications. Each bearing reaches 2.5 m in height, and its mass is almost 25 tons.
