Bearing system life (the calculated life of the combined system of bearings in the pump) shall be equivalent to at least 25,000 h with continuous operation at rated conditions, and at least 16,000 h at maximum radial and axial loads and rated speed. This section contains a discussion of t...
In the United States, the American Bearing Manufacturers Association (ABMA) defines the Basic Rating Life, B10 or sometimes referred to as L10, as the bearing life associated with a 90% reliability when operated under conventional conditions. Stated another way, it is the amount of time 90% of...
The rating life of a bearing is referred to as L10 life. Fig. 11.3 shows bearing rating life plot with average life means that 50% of bearing will complete and 50% of bearing will fail before rated life. The life of a bearing depends on load. Consider two groups of bearings that ...

Contrary to this approach, the proposed model makes use of a L10 life associated to a 90% reliability for the gear population. Comparison between the experimentally obtained gear endurances and L10 predicted life, using the present theory, indicates the ability of the model to account for the ...
