The recommended class of fit for the journal and the bush of a hydrodynamic bearing is 40H6-e7. The dimensions of the journal and the bush are normally distributed and the natural tolerance is equal to the design tolerance. From the considerations of hydrodynamic action and bearing stability, the maximum and minimum clearances are limited to 0.08 and 0.06 mm respectively.
Determine the percentage of rejected assemblies.
