摘要

ESTL carried out a ball bearing life test programme inrnsupport of the development of the Metosat ThirdrnGeneration Infrared Sounder (MTG IRS) instrumentrn[1]. Two ball bearing pairs were tested simultaneouslyrnin the same vacuum chamber. One pair was solidrnlubricated (sputtered MoS_2 applied to the balls andrnraceways) and the second fluid lubricated usingrnFomblin Z60 oil.rnThe test results indicated that the torque performancernof the fluid lubricated ball bearings was superior to thatrnof the solid lubricated bearings. It was concluded thatrnthe fluid lubrication represented the most appropriaternsolution provided any potential contamination riskrnresulting from oil evaporation was acceptable.
