Operation and peripheral parts of EDA bearing equipment regular maintenance and replacement are disassembled thrust angular contact ball bearings are examined, in order to determine the EDA bearing parts can be used and record the use of good from bad again. But also carefully investigated and documented bearing and appearance were removed. In order to understand and investigate the remaining amount of lubricant, after sampling, to properly clean the bearings.

EDA bearings
Secondly check EDA bearing raceway surface, rolling surface and surface condition and cage wear, no damage and anomalies in particular to observe the running track of the raceway surface. Determine the angular contact thrust ball bearing can be used again, to bearing damage degree, the machine performance, importance, operating conditions, such as checking cycle later decided.
Check the results, if it is found that the EDA bearing damage and abnormal situation, please follow the bearing damage phenomenon to find out the reasons, measures. In addition, inspection results, if there are some defects in it, thrust angular contact ball bearings can not be used, need to replace new bearing.
