ABSTRACT:
Thrust bearings need to be under axial load to prevent skidding of the balls in the races. In a gas turbine engine, the thrust bearings between relatively rotatable shafts can experience zero load as engine conditions vary. A permanent load is therefore applied by causing an extension 38 of cage 22 to run in an oil reservoir 30. The resultant drag applies a torque to the cage and affects its speed of rotation relative to that of the shafts 10 and 14.
