August 20, 2012
Setting the proper LOR is essential to be able to separate closely spaced defect frequencies. An example would be a pump with 5 vanes that could generate a “Vane Pass” frequency equal to the number of vanes, or 5 times rotational speed; if the impeller end of the pump had an SKF 7301BEP bearing, it could […]
