When removing the damaged bearing before

1 Review the bearing load and calculation speed and other raw data and pay attention to whether the original design omissions or errors Check the actual load of the bearing and rotating speed and whether there is a discrepancy if the original design of bearing selection is correct.

2 Understand the damage and the anomalies near the end of damage especially the emergence of the noise and fever status and evolution; Check the power supply as well as the bearing of the adjacent in the presence of abnormal phenomena during mechanical components.

3 Analysis of the types of noise high and low tones the interference of frequency rhythm pay attention to when the sudden temperature increase appears and so on to write down the situation of power supply and other parts

4 Figure out the configuration characteristics of bearing in the host and cooperate with the characteristics determine whether its configure properly write down the ring relative to the location of the shell and the position in relation to the direction of the load.The shaft by hand turned a few rounds with damaged bearing test to experience heavy degree and then along the axial shaft driving back and forth a few times to experience axis along the axial tightness measuring the deflection of shaft when necessary

5 Check the bearing parts find out the lubrication; Condition and pollution situation whether the lubricant brand and sealing way is wrong to pay attention to temperature if bearing temperature is more than the temperature limit of lubricant used check the oil level whether the oil seal clearance leakage and moisture dust or other foreign material whether has invaded bearing and if oil system has fault.

6 See whether there is influential to bearing vibration source.Debris or particle source pollution sources water or fluid can through the bearing current source depending on the check can be used as a basis to determine the bearing of the damage was due to micro corrosion abrasion corrosion or electric erosion.
When removing the damaged bearing

1 check the appearance of the sealing device after it is removed until thoroughly to identify the cause of the damage before to clean or change new when necessary will be attached to the contamination sampling inspection tests to ascertain the dirt category find out the reason and pollution sources of this pollution examined the sealing device has damaged axis rotation week in your hands see whether seal tightness and seal clearance evenly whether dry friction; Research the abrasion condition of the sealing lip.

2 carefully remove the bearing and will remove the bearing with the attached lubricant or pollutants as well with plastic paper bag for future reference take note of the bearing code manufacturer and compute the real life of the bearing.Pay attention if disassembled is arduous especially loose or tight pay attention to don't leak related bearing clastic grease stain and dirt etc.
