Tests of Dry Composite Lubricated Bearings for Use in an Aerospace Environmental Chamber

摘要

The report contains the results of a test program set up to determine the operational characteristics of dry composite lubricated bearings. Two different bearing types were tested: Tapered roller bearings and ball bearings. Four dry composite lubricants and two low vapor pressure greases were tested. Results indicate that the dry composite lubricants were more successful when used with ball bearings than when used with tapered roller bearings. All four composite lubricants provided low system torques (40 to 60 lb-in.) under heavy loads (3000 lb/bearing) for the scheduled 100 hours. (Author)
