This paper describes plant experience and supporting research work for steam turbine casing expansion bearings as used in the Central Electricity Generating Board. Problems with greased bearing supports are discussed and the evaluation of a number of dry bearing materials, over a wide temperature range, is detailed, including data for friction and specific wear rates.
