In the theoretically (design) life is the fatigue life of the bearing, under normal conditions of use it represents the wear life of the bearing; However, when the use conditions are not normal, or the manufacture, design defects, actually represents the bearing failure of life. But in the actual statistical work, the service life is the sum of three no longer hierarchical, and thus become the the inclusive three kinds of life manifested bearing life.
Key is associated with the life of the bearing failure, as well as bearings peeling, pitting, and this is typical of the fatigue damage. As can be seen from here, peel fatigue failure bearing scrapped when a secondary factor in this case: in our existing manufacturing, use conditions, bearing rating based on the phenomenon of bearing fatigue life, real life, theoretical fatigue life of the average lifetime, a far cry from the actual statistical failure life. This life only as a potential capacity of the bearing parts or bearing reliable sign.
Incidentally, in some special cases, the bearing life is determined by the specific conditions. Such as testing equipment, coordinate it the pumping Order of the bed, grinders and other equipment based on the bearing accuracy can meet the expected machining accuracy whether Liu Ding reported Geng, some bearing its noise Can guarantee the expected movement of love to determine whether the scrap, called specific lifetime.
