6 common causes of machine vibrations — Istec

16/10/2018· Each part of a roller bearing has its own frequency. By calculating these frequencies, it is possible to use vibration analysis to determine whether the vibrations are a result of bearing damage. In contrast to roller bearings, sleeve bearings do not use a rolling element, but use a fluid (oil) film to reduce friction.
