Number of rolling bearing life to go (or in a certain number of hours of work speed) definition: within this life of bearings, in any of its initial fatigue damage on the rings or rolling elements of bearings (peel or defect). However, in laboratory testing, or in actual use, are clear to see, in the identical bearings under the same working conditions, real life is quite different. In addition, there are several different definitions of the bearing of "life", one of the so-called "working life", represents a certain bearing on real life can be achieved before the damage is determined by wear and damage usually is not caused by fatigue, but rather caused by wear and tear, corrosion, seal damage and other factors.

As a standard for determining bearing life, linked to the life and reliability of bearing.

Due to manufacturing precision, uniformity of material differences, even if it is the same material, same bearings of the same size and in the same job under the conditions of use, and their length of life is not the same. If the statistical life expectancy of 1 unit of relative life expectancy is 4 units long, the shortest is 0.1-0.2 units, the longest and the shortest life expectancy of more than 20-40 times. 90% bearings are not pitting, revolutions or hours of experience called bearing rating life.
