A lot of experienced mechanical maintenance technicians will usually run the sound through the machine to determine whether the device is normal, Tianjin Han Huang Precision Trade Co., Ltd. technical staff to summarize past experience bearing on the motor used to analyze the sound for example. 1, a continuous buzzing sound "hum ...":Analysis: Motor no load operation is to issue similar to the buzzing sound the same, and the occurrence of axial motor abnormal vibration, open or shut down the "Om" sound.

1, plastic bearings and the phenomenon does not occur in rust resistant and rust metal bearing can not be used for chemical liquid;
2, plastic bearings are lubricated materials overall, long life; while FAG bearings lubricated metal sliding surface layer is only 0.003mm of PTFE, a thin layer of friction when it finished pluralism and the end of life;3, plastic ntn Bearing manufacturing cost is lower than the metal;
