what is the best way to detect the shaft wear under the bearing inner race or under the sleeve specially i face many problems like that but the only frequency shown in the spectrum is 1XTS.
variable speed motor (rated speed 1485 rpm)
dominant frequency 1XTS (H=10 mm./sec....Vertical=6 mm./sec.....A=4 mm./sec)
after balancing the vibration dropped to 2 mm./sec but in two days the vibration reached 36 mm./sec at horizontal direction 1XTS dominant
vertical 25 and axial 8 but dominant is 3XTS
please take a look at the attachement
Shaft photos and measurement points after symptom being very effective
