Improvement of Solid Film Lubricants and Unlubricated Bearing Operation

Abstract

Results are presented for the performance of unlubricated ball bearings operating at 1750 rpm in a vacuum of 10(exp-7) Torr or less. One precision bearing is still operating after 7000 hours under these conditions. The wear life improvement of solid film lubricant by means of various techniques is discussed. These techniques include double deposition, plasma spraying, metal coating of lubricant powders, and compacting. Improvements of as much as a 50 fold increase have been achieved.
