The effect of the number of rolling elements on the radial vibration spectrum expressed in octave bands is shown experimentally. Vibrations of 6305 bearings in axial direction were studied at various loads and speeds. Radial vibration spectra of 6322, 6312, 6305 and 6203 bearings were recorded for determination of outer ring resonances comparison to theory is made. Narrow band spectra were taken showing the fine structure of a 6305 and 6312 bearing vibration spectrum. The status of procurement of bearings with improved smooth running characte31stics both large roller bearings and small Amend ment 3 bearings is reported. Waviness measurements on large roller bearing races are reported and a newly installed vertical wavo meter is described. Some experiences gained during trial runs of the newly installed large bearings vibration tester are reported. Author
