Failure Rate Estimates for Mechanical Components

Conversely, if the bearing is replaced every 2 years, the failure rate will vary between 0 at "time zero" to 19 FPMH at the two year point, with the average failure rate estimated to be 14 FPMH, as represented by the green line in the right-hand figure. Because average component failure rate is constant for a given maintenance renewal concept
