A 02-series deep - groove ball bearing is to be selected to carry a radial load of 8 kN and a thrust load of 4 kN. The desired life LD is to be 5 kh with an inner-ring rotation rate 900 rev/min. The manufacture's catalog on the basis of 10° revolutions for rating life and the Weibull parameters are xo=0.02, 0=4.459, and b=2. Determine the mean, median, the 10th percentile life, the slandered deviation, and the coefficient of variation. What is the basic load rating and the reliability that should be used in selecting a bearing for a reliability goal of 0.90?

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the s…
