We have a issue on Bag Filter fan Drive Bearing, It has been running on high temperature for last month. Around 100 degree C. It was replaced before three months, After a right quantity of greasing its temperature remains high. I can see there is no High G's Value or early signs of bearing in a peakVue, Infact there is a little resonance ( wobbling ) in one belt. Bearing BPFO Peaks are not matching a little difference with matched lines, there is not high temperature on pulleys or shaft. So what could be the reason of High temperature???
Motor RPM = 1480 Belt Driven Fan RPM = 1650, 5 belts V type.
I have attached spectrums & information, Need your Opinions guys ???
Thanks in Advance
