Solution
The designers finally decided in favour of using
iglidur bearings in the ring motors, which were able to solve the problems permanently. The polymer bearings are suitable for use in and on underwater vehicles and boats due to their corrosion resistance, low moisture absorption and lightweight property compared to metallic solutions. Compared to ceramic bearings, the iglidur bearings also offer the advantage that they have a high load limit and are highly wear-resistant. While initial tests with impacts caused problems with the ceramic bearings, the special bearings made from high-performance polymers remained dimensionally stable over the long term. Another important criterion for dynamic fields of application.
