The fatigue life of a bearing is defined by the number of revolutions the bearing will operate before the first signs of fatigue occur. The L 10 life is the basic rating life in hours that 90% of a sufficiently large group of apparently identical bearings will operate before the first signs of fatigue appear.

Webof failed bearings. The first bearing fails after about 30⋅ 10 6 revolutions, and the last one after 1,800⋅ 10 6 revolutions. The result is a factor of 60 from the first to the last! The L 10 life-time in this case— where 10% of the bearings failed and 90% are still working— would be about 120⋅ 10 6 revolutions. This

The most commonly … WebThe B10 life metric originated in the ball and roller bearing industry, but has become a metric used across a variety of industries today. It’s particularly useful in establishing warranty periods for a product. The “BX” or “Bearing Life” nomenclature, which refers to the time at which X% of items in a population will fail, speaks to these roots.
