Abstract
The paper summarizes the experience of development and application of high-speed sliding bearings for centrifugal pumps of ship energy units, thermal electric stations, and nuclear power plants. The operation of sliding bearings involves superheated water to temperatures of 200°С and at sliding velocities of 20–40 m/s. Unlike metals, these sliding bearings need no additional oil lubrication. Two antifriction carbon plastics, namely, phenolic type FUT-B and new polyphenylene sulfide type UPFS, are discussed.
