Bearing Calculator

This calculator makes use of a bearing's RPM (revolutions per minute) to find the correlation between temperature and speed as well as vibration and speed. If you would like to calculate the correlation between a bearing's RPM and its vibration, simply enter the speed in the input box below and click the first 'submit' button. Alternatively, if you would like to calculate the correlation between a bearing's RPM and its temperature, make sure to also fill out the rest of the fields and click the second 'submit' button.
