SKF bearings calculation method and test method for fatigue life estimation of Cham in two ways.
　　Required formulas and calculation rules calculated fatigue life of bearing fatigue life calculation, calculate the total transfer value provision for inner ring or shaft washer turn (outer ring or washer is fixed at this time), the total transfer value.
　　In accordance with our standard test methods (rolling bearing fatigue life test procedures), performance can meet the requirements of the tests specified for the approach, to sample group of SKF bearing fatigue life test, obtained from the experimental data processing of actual test of life, which is represented in subjects bearing the bearing fatigue life.
　　Lubrication of rolling bearing fatigue life test on the sample is fully maximize factors inhibit the wear of rolling bearings, and speed in order to highlight the use of enhanced load bearing fatigue life of an enhanced test method for fatigue factors.
　　SKF bearing fatigue life calculation of fatigue life test and complement each other, both results of a sufficient number of correspondence.
　　Actually, as on each a specific of using occasions, are extraction enough number of bearing for life test, to validation by selected bearing is suitable, this in economic Shang, and time Shang and labor Shang are is is vast of, so bearing life of test method just in is necessary or important of situation Xia only using, in most situation Xia, used standard of life calculation method to estimated SKF bearing of using life, has enough degree of can dependence.
