Is 1x change when we go for Balancing with damaged bearings .Today i had balanced a FRP fan statically ( customer requested to balance in static ) , 20 @ 180 degrees grams added at base plate and 80 grams @ 0 degrees added at shroud and no sign of abnormal shaking and fan stand still at its full speed except damaged bearing noise ( Fan base in worst condition ).
1x value normal at D.E bearing with 2.5 g Peakvue value .
1x value 10 mm/sec at N.D.E bearing with 6.5 g peakvue value .
I recommend them to change both bearings for further Dynamic balance corrections .
Need your valuable comments .
