Bearing inspection and judgment

In order to judge whether the removed bearing can be reused, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance, mating surface, raceway surface, cage, and sealing ring. Because large bearings cannot be rotated by hand, pay attention to checking the appearance of rolling elements, raceway surfaces, cages, rib surfaces, etc. The higher the importance of the bearing, the more careful inspection.

How to ensure the reliable operation of bearings

In order to give full play to the bearing and maintain its due performance for a long time, it is necessary to do regular maintenance (regular inspection). Through appropriate regular inspections, it is very important to improve productivity and economy to detect faults early and prevent accidents before they occur.

Dynamic bearing load rating

In order to compare the bearing capacity of the bearing against pitting corrosion, when the rated life of the bearing is specified as one million revolutions (106), the maximum load that can be carried is the basic dynamic load rating, denoted by C.

That is to say, under the action of the rated dynamic load C, the reliability of this kind of bearing working for one million revolutions (106) without pitting failure is 90%. The larger the C, the higher the carrying capacity.
