Long Life Ball-Bearings for Use in Satellites in Sealed Containers

Abstract

The Report concerns the development of long life ball bearings with one initial lubrication. The knowledge of many experts was pooled and an experimental batch of 60 spindles fitted with several types of ball races was run for seven years. The conclusion is that a 10 year life should be reliably obtained for such devices as momentum or reaction wheels for satellite attitude control. Significantly longer reliable lives are probably possible.
