When inspecting the deep groove ball bearings disassembled during the regular maintenance, operation and replacement of peripheral parts of the bearing equipment, it is necessary to judge whether the secondary bearing parts can be used again and record whether the use is good or bad. Also carefully investigate and record the removed bearings and their appearance. In order to clarify and investigate the remaining amount of lubricant, after sampling, the bearing should be cleaned well.
Secondly, check the raceway surface of the deep groove ball bearing, the condition of the rolling surface and the mating surface, and the wear state of the cage for damage and abnormal conditions, especially to observe the running track of the raceway surface. To judge whether the bearing can be used again, it should be decided after considering the degree of bearing damage, machine performance, importance, operating conditions, inspection cycle, etc.
Check the results, if the bearing is found to be damaged or abnormal, please find out the cause according to the phenomenon of bearing damage, and formulate countermeasures. In addition, the inspection results, if there are the following defects, the bearing can no longer be used, and a new bearing needs to be replaced.
How to ensure that the deep groove ball bearing is normal during use, how to keep the bearing free from damage and make the bearing life longer. Let me explain to you the precautions for ensuring the reliable operation of bearings. I hope it will be helpful to you.
In general, the precautions for ensuring the reliable operation of certified bearings have the following requirements:
a. Any one of the inner and outer rings, rolling elements, and cages has cracks and debris.
b. Any one of the inner and outer rings and rolling elements is peeled off.
c. The raceway surface, ribs, and rolling elements are obviously stuck.
d. The cage is severely worn or the rivets are loose.
e. Rusted and scarred raceway surfaces and rolling elements.
f. There are obvious indentations and marks on the rolling surface and rolling body.
g. There is creep on the inner diameter surface of the inner ring or the outer diameter of the outer ring.
h. Discoloration due to overheating.
i. The sealing ring and dust cover of the grease-sealed bearing are seriously damaged.
