Abstract
The diametral variations around the circumference of a bearing roller are measured by mechanical-to-electrical transducers which convert the diametral variations into electrical signals which are functions of the variations. The frequencies of the electric signals are converted into electric spikes which are proportional to the actual effect on roller noise of the frequency represented by each spike. The spikes are electrically added and a print is made of a value which is proportional to the expected noise the roller will produce when used in a roller bearing.
