Abstract : Operation of a facility for measuring cage and inner race temperatures of lightly-loaded 20-mm angular-contact ball bearings at high speed and vacuum is described. Results of tests on 440C ball bearings with MoS2-epoxy compact cages at 300 F and with Niresist cages coated with MoS2-graphite-sodium silicate solid film at 600 F are given. The latter bearings, for the short (about 1 hour) test time, ran smoother and with less raceway damage than did the bearings with the epoxy-MoS2 cages. (Author)
