WebThe smoothness or quietness of a bearing can be checked by accelerometers which measure bearing vibration at the outer ring, usually with the inner ring rotating at 1800 rpm. To understand how bearing vibration is measured, it is important to understand how vibration works. The amount of oscillation in a vibrating object is called displacement. http://www.frantz-mfg.com/product_detail.aspx?id=236
