WebReply with quote. #2. In my somewhat limited experience (maybe 10 cases) with fluting there is a lot of high frequency in the early stages of a problem and as the bearing distress progresses the typical bearing frequencies become more evident. I'm used to seeing, early on, a haystack often centered at about 3 kHz. WebDec 9, 2013 · Bloom agreed that adding a grounding ring to the shaft is an effective way to prevent electrical fluting. “Some motor manufacturers are now grounding shafts from the factory,” he added.

WebElectric Pitting/Fluting Damage. As electric currents pass through bearings, they create an arc and burning at the points where it jumps an air gap. Pitting, also known as fluting, damage is caused by abnormally larger charges of electricity. Cracks. Cracks most often occur when bearings aren't properly mounted and installed.
