When inspecting the deep groove ball bearings that have been disassembled during regular maintenance and operation of bearing equipment and replacement of peripheral parts, it is necessary to determine whether the secondary bearing parts can be reused and record whether the use conditions are 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, the bearings should be cleaned well after sampling.
Secondly, check the raceway surface of the deep groove ball bearing, the condition of the rolling surface and mating surface, as well as the wear status of the cage, etc. for damage and abnormalities. In particular, observe the running trajectory of the raceway surface. To determine whether a bearing can be used again, the decision must be made after considering the degree of bearing damage, machine performance, importance, operating conditions, inspection intervals, etc.
According to the inspection results, if the TIMKEN bearing is found to be damaged or abnormal, please identify the cause according to the bearing damage phenomenon and formulate countermeasures. In addition, according to the inspection results, if there are any of the following defects, the bearing can no longer be used and needs to be replaced with a new one.
How to ensure that deep groove ball bearings operate normally during use, and how to ensure that the bearings are not damaged and have longer service life. Let me explain to you the precautions to ensure the reliable operation of bearings. I hope it will be helpful to you.
Things to note when undertaking reliable work include the following requirements:
a. There are cracks and fragments in any of the inner and outer rings, rolling elements, and cages.
b. Any of the inner and outer rings or rolling elements is peeled off.
c. The raceway surface, ribs, and rolling elements are obviously jammed.
d. The cage is severely worn or the rivets are loose.
e. The raceway surface and rolling elements are rusted and scarred.
f. There are obvious indentations and scratches on the rolling surfaces and rolling elements.
g. There is creep on the inner diameter surface of the inner ring or the outer diameter of the outer ring.
h. Severe discoloration due to overheating.
i. The sealing ring and dust cover of the grease-sealed bearing are seriously damaged.
