Reduce Force to Maximize L10 Bearing Life

| | | |

By on August 17, 2016

Simply put, L10 bearing life is the number of service hours that 90% of bearings will survive or conversely 10% of bearings will have failed. L10 life: is the preferred term in specifying bearing life and is defined by The American Bearing Manufacturers Association (ABMA). A bearing life equation is: This calculation assumes proper installation […]
