Structure-borne vibration test results of the seventeen, size 310, deep-groove, rolling con tact, ball bearings are presented. The ex perimental apparatus and its associated in strumentation used for this test program are described in detail. In these tests, the free outer ring was subjected to an axial load of 30 pounds while the inner ring was rotated at 1800 rpm. All-pass and narrow-band 4 acceleration-frequency analysis data were ob tained for all bearings using two sub-miniature accelerometers secured to the free outer rings at particular locations to determine both radial and axial acceleration. All of the frequency analysis strip charts obtained are included in the Appendix of this report. In addition, numerous charts, graphs, tables, etc., are presented to make various comparisons of the data obtained. Although the requested bearing geometrical data for these bearings is non existent at the present time, it was possible to draw a number of meaningful conclusions based on the data obtained. The most significant conclusion was that all bearings tested exhibited the same principal frequencies, virtua all of which are able to be accounted for. Author
