Analysis of the Impact of Ball Bearing Track Waviness on Their Frictional Moment

Frictional moment is one of the parameters that determine the time and quality of working bearings. Therefore, it is important that it is possible to accurately predict the value of the frictional moment. This article analyses the impact of the track waviness on the frictional moment. In the research, a correlation analysis of selected wavelength parameters and frictional moment was performed and frictional moment. Those parameters wavelength are not included in the models used to determine the theoretical value of the frictional moment.
