L10 Bearing Life

According to the Anti-Friction Bearing Manufacturers Association Standards, the rating life L10 of a group of apparently identical ball bearings is the life in million of revolutions that ninety percent (90%) of the group will complete or exceed.

Since pumps tend to run at a constant speed, pump manufacturers express the L10 life of pump bearings in years rather than revolutions.
