Axial angular contact ball bearings because even a slight peeling and other damage, abnormal tone will be issued irregularly sound, hence the sound measuring device can be resolved using sound measuring device, for operation of the thrust angular contact ball bearings rolling sound size and quality to be checked, played the role of prevention in advance.
From peeling, creasing, corrosion, cracks, wear, etc. will be the thrust angular contact ball bearing vibration measurement reflected view, INA Bearings vibration of the bearing damage is very sensitive, so, through the use of special bearing vibration measurements ( frequency analyzer, etc.) to measure the size of the vibration, frequency points can not be inferred abnormal circumstances. Since the measured values due to thrust angular contact ball bearings conditions of use or sensor installation location is different, so each machine needs prior to analysis and comparison of the measured values determined criteria.
If the hole can be measured directly using the angular contact thrust ball bearing outer ring temperature is more suitable position. Generally, the bearing temperature, generally based on the temperature outside the bearing chamber can be inferred. If lubrication, install the appropriate department, then thrust angular contact ball bearings abrupt temperature will rise, there will be an abnormally high temperature, time to stop running, take the necessary precautions.
Axial angular contact ball bearings for regular equipment maintenance, inspection and peripheral parts replacement operation was dismantled when INA bearings checked seq judgment can be used again or use of good or bad. To carefully investigate and document split down the bearing and appearance, and in order to understand and investigate the remaining amount of lubricant, sampling after a good wash to thrust angular contact ball bearings.
Second, check the raceway, the raceway and the mating surface of the situation and the state of wear of the cage and other signs of damage and anomalies.
Determine the thrust angular contact ball bearings can be used again, to consider the extent of damage INA bearings, machine performance, the importance of operating conditions, inspection cycles and then later decide. Test results, if found bearing damage and abnormal conditions, it should first identify the reasons to develop countermeasures to prevent a thrust angular contact ball bearings affect the normal use.
